October 2017 - Recent papers on Wealden fossils from West Sussex
Two recently published papers describe significant fossil finds from the Wealden rocks of West Sussex.
The first is a paper about terrestrial vertebrate fauna from a bone bed in the Wealden of the Ardingly area. Unusually the fossils derive from sandstone blocks found ex situ in 2012 during building excavations at Ardingly College. Sedimentological investigations show that the blocks are from the Hastings Group, Ardingly Sandstone as well as the Grinstead Clay which underlies the building site. The bed containing the most abundant vertebrate fossils probably represents the top Lower Tunbridge Wells pebble bed. Exposures of Ardingly Sandstone at Wakehurst Place, one of our Local Geological Sites, and Balcombe Lane, Ardingly were studied together with local borehole and pit data to confirm the identification of the sandstone blocks.
A tooth from an ornithischian dinosaur appears to represent a new taxon for the Wealden Supergroup. Teeth of the crocodilian Theriosuchus extend the known range of this taxon in the Wealden, while teeth of an ornithocheirid pterosaur confirm the presence of these animals in the skies above the Wealden basin.

The second is a paper about fish otoliths found over a period of 10 years in the lower Weald Clay at Langhurstwood Quarry, one of our Local Geological Sites, and also at nearby Clockhouse Brickworks in Surrey. Otoliths are calcium carbonate infillings secreted in the inner ear of vertebrates. These recent finds represent otoliths from the saccular part of the inner ear of freshwater fish. Their form is species-specific and they can be used to identify taxa. Many of the specimens are densely packed on individual bedding planes and are interpreted as coprocoenotic accumulations, having passed though the digestive tracts of predators and been subsequently excreted in quantity. Other parts of the predated fish would probably not have survived the digestion process.
Two new species are defined, Leptolepis wealdensis and Leptolepis toyei, which is named in honour of Sussex geologist the late Geoff Toye in recognition of his outstanding contributions to the palaeontology of the Wealden rocks.

September 2017 - New zonation of lower Campanian chalks of southern England based on microcrinoid fossils and new species named in honour of Sussex geologists
A new paper in press by Andy Gale of the University of Portsmouth describes a distinctive succession of pelagic microcrinoid faunas in the lower Campanian chalks of Sussex, Hampshire, Isle of Wight and Dorset. He proposes a new zonation which provides an independent interpretation of the regional correlation of the Newhaven, Culver and Portsdown chalk formations, previously based on correlation of flint and marl marker beds.
Amongst the key microcrinoid species described is a new species which he has named Hessicrinus cooperi in honour of John Cooper of the Booth Museum, Brighton, who did much to help his work on chalk fossils. Images of Hessicrinus cooperi are shown in Figure 4 of the paper.
John is the founding father of geoconservation in Sussex and it is worth noting that most of the sites in Sussex which provided material for Andy Gale’s research are designated as Local Geological Sites (formerly RIGS) and are still accessible. They comprise coastal cliffs and inland chalk quarries.

In an earlier paper published in 2016 Andy Gale described the discovery of an abundant, diverse and largely undescribed microcrinoid fauna from the lower Campanian chalk of southern England and compared it with similar microfossils from the lower Campanian of Texas, Mississippi and southern Sweden. A number of new genera and species were identified including the species Costatocrinus mortimorei named in honour of the stratigraphical work of our local and international Chalk expert, Rory Mortimore, on the chalk of the Anglo-Paris Basin. Images of Costatocrinus mortimorei are shown in Figure 4 of the paper.

September 2017 - Giant Dinosaur Model for Lewes
A proposed project to install a giant dinosaur model in Lewes will be officially launched at the Lewes Fossil Fair on 16 and 17 September 2017
It would provide an impressive memorial to the achievements of Dr Gideon Mantell, the surgeon and geologist who was born and lived in Lewes. In 1822 he and his wife Mary found the fossilised remains of the first recognised dinosaur, later named Iguanodon.
The proposed life-sized resin model would be 3 m high and 7 m long and an internationally renowned model maker in America is currently working on a scaled-down prototype. The model will be on view at the Depot Cinema on 16 September to tie in with a showing of 3D Jurassic Park. It will then be on view at the Fossil Fair on 17 September and possibly after that at the Linklater Pavilion.
At the launch the directors of the Lewes Dinosaur Project will invite suggestions on possible locations for the giant dinosaur.
Lewes Fossil Festival Weekend
Saturday 16 September: 3D Jurassic Park at the Depot Cinema 4:00 pm
Sunday 17 September: Fossil Fair at the Linklater Pavilion 10:00 am to 4:00 pm, including Nicky Dee and the Special Dinosaurs workshop and reading 11:00 am to 1:00 pm
July 2017 - A new dinosaur find from Smokejacks Pit in Surrey
A news item in the Guardian reports the finding of a new fossil dinosaur in February at a brick pit in Surrey. The site, Ewhurst Brickworks, is owned by Wienerberger and is also widely known as Smokejacks pit.
A nearly complete skeleton of a species of Iguanodon has been removed for investigation and cleaning at the Fossils Galore museum near Peterborough where the public can see the process at work. It is very rare to find a nearly complete dinosaur skeleton in the UK and this specimen will eventually go on display.
Smokejacks pit has yielded a number of important dinosaur fossils. It is most famous for the finding of a new theropod dinosaur Baryonyx walkeri in 1983.
May 2017 - New Natural History Museum Fossil Explorer mobile app
Spring has finally arrived in the UK, and now is the time to get out and look for fossils.
The Natural History Museum in London has just released a new version of the free Fossil Explorer app, a field guide to the common fossils of Britain that helps identify fossils based on where they are found.
Whether seeking ammonites in Lyme Regis, marine reptiles in Whitby or trilobites in Girvan, beginner and more experienced collectors alike can learn about their finds and what else may be beneath their feet.
Through Fossil Explorer, users have access to the combined expertise of the Natural History Museum and the British Geological Survey. Based on information from the Museum's popular British Fossils book series, the app offers details about more than 1,200 fossil taxa as well as local geology.
Thanks to an interactive geological map, Fossil Explorer suggests likely fossil matches based on where they are found, giving a list of fossils known to occur in rocks of the same age. Introductory facts and illustrations help beginner fossil hunters get started, while additional information enables more experienced fossil collectors to delve deeper.
New functionality in this release allows users to create and share lists of fossils they have found and set wish lists for future discovery.
We hope the app will encourage budding citizen scientists around the country, inspire a new generation of explorers and get people thinking differently about the natural world.
The app is available for iOS and Android. More information and download links are available on the Museum's website at www.nhm.ac.uk/fossilexplorer.
April 2017 - The most recent Geo Brexit
A blog by Peter Campbell in the Guardian adds to the story of past Brexits (or Geo Brexits) covered in our previous news item (below).
Actually this is mostly about the most recent separation of the British Isles from continental Europe which took place about 8000 years ago. This was the time when sea level rose after the end of the last Ice Age and gradually flooded the Channel and the extensive low lying Doggerland across the North Sea. It was a time of great significance for archaeology because Homo sapiens had by then arrived in what became the British Isles. So archaeologists are now looking for evidence of past landscapes beneath the Channel and the North Sea and associated evidence of human occupation.
April 2017 - The first Brexit
Dr Jenny Collier and Professor Sanjeev Gupta at Imperial College have just announced the latest results of their research on mapping and interpreting high-resolution bathymetric data from the Channel.
Ten years ago they showed the presence of giant valleys in the sea floor in the central part of the Channel and proposed that they were evidence of a megaflood 450,000 years ago, caused by a catastrophic breach in the chalk land bridge (the Weald-Artois anticline) connecting Britain to the continent. This occurred during the maximum extent of the Anglian glaciation and they proposed that the most likely cause of the megaflood was the overflow from and emptying of a very large proglacial lake covering the southern North Sea area at that time.
The new study by the team, working with their colleagues in Europe, now shows for the first time the details of how the chalk ridge between Dover and Calais was breached. New geophysical data in the eastern Channel and Dover Strait collected by colleagues from Belgium and France has been combined with seafloor data from the UK showing evidence of huge holes and a valley system located on the seafloor. The chalk ridge formed a huge dam which was eroded and weakened by giant waterfalls. Ultimately this resulted in failure of the dam and release of huge volumes of water. The holes in the sea floor appear to be plunge pools created downstream by the water cascading over the chalk dam.
The research has also found evidence of a second megaflood, possibly 250,000 years ago.
When the dam was breached at the time of the Anglian glaciation the sea level was low and the Channel area was dry land but in the subsequent warm period, the Hoxnian interglacial, sea level rose as the ice sheets melted and the first marine connection was established through the Dover Strait. This was the first of several "Brexits". Since then the changes of sea level through successive cold (glacial) and warm (interglacial) periods have caused land connections with the continent to alternate back and forth with fully marine conditions in the Channel and Dover Strait.

March 2017 - Irresponsible fossil hunters on Rother District beaches
Rother District Council's cabinet recently discussed a proposed fossil collecting code of conduct drawn up by the Bexhill Museum. The need for a code has arisen following incidents of commercial and irresponsible fossil collecting creating damage to the beach environment and constituting a loss of important heritage material.
A news item in the Bexhill-on-Sea Observer drew attention to the meeting:
Details of the proposed fossil collecting code of conduct are provided in a report to the cabinet (106kB) dated 13 March 2017 which recommends that the Council approve the code.
March 2017 - Wealden Sandstones
A study of the porosity and permeability of selected Wealden sandstones is the subject of a recent paper by Oladapo Akinlotan at the University of Brighton.
Akinlotan, O., 2016. Porosity and permeability of the English (Lower Cretaceous) sandstones. Proceedings of the Geologists' Association 127, 681-690.
The study is based on samples of sandstones within the Ashdown and Wadhurst Clay Formations of the Weald Basin. Samples were collected from SSSI coastal sites in East Sussex at Rock-a-Nore (Hastings) and Haddock's Cottages and Cliff End (Pett Level) with permission from Natural England. These sites are also designated as Local Geological Sites (Foul Ness, Fairlight Cove and Cliff End).
The lower Ashdown Formation was sampled at Rock-a-Nore, the upper Ashdown Formation at Haddock's Cottages and the uppermost Ashdown Formation and the Cliff End Sandstone in the lowermost Wadhurst Clay Formation at Cliff End.
Porosity ranges between 6.3 and 13.2% (average 9.9%) and permeability ranges from 0.4 to 11.9 mD (average 3.1 mD). The main controls on porosity and permeability are grain size, grain shape and degree of sorting which are directly linked to their fluvial depositional environments.

Date: 10 March 2017
Leader/Facilitator: David Bone
OUGS Organiser: Jeremy Cranmer
Contact email: firstname.lastname@example.org
Tel: 07531 318314
Aim of Event: A growing demand on the supply of clean water is balanced by ever increasing constraints on the discharge of wastewater to the environment. We shall study how this achieved.
1. Twyford Water Supply Works and Twyford Waterworks
2. Phoenix Inn, Twyford
3. Morestead Road Winchester Wastewater Treatment Works
Start location: Twyford Water Supply Works / Waterworks, Hazeley Rd, Twyford SO21 1QA
Grid Ref.: SU493250
Courtesy of Southern Water and Twyford Waterworks Trust, we start with a visit to the operating Water Supply Works and the historic Twyford Waterworks to understand the processes behind water abstraction from the Chalk aquifer and putting it into supply. The visits will be complemented at lunchtime by talks from the Environment Agency at the Phoenix Inn, Twyford, on how these activities interact with the hydrogeology of the Chalk and the environmental constraints that need to be taken into consideration. In the afternoon, courtesy of Southern Water, we visit Morestead Road Winchester Wastewater Treatment Works. We will see how wastewater is treated to a high standard before discharge and recharge of the Chalk aquifer. This is the largest waste discharge to groundwater in the UK.

Approx. Finish time: 1600 hrs
Lunch and Toilet Arrangements: Lunch will be taken as a Ploughman's lunch at the Phoenix Inn which is included in the cost of the trip (£10.00)
Field/Safety Equipment Needed: Sturdy and waterproof footwear. Hi-viz vest (provided by the Branch). Hard hat. Gloves (for use at the wastewater treatment works; rubber or disposable will suffice).
January 2017 - Current status of Novington Sand Pit
The quarry was still being worked in 2012 but it has now been unused for about 4 years due to economic constraints. The operator Dudman Group had permission to extract remaining sand and complete restoration by 2 October 2016.
In September 2016 Dudman Group applied to the South Downs National Park Authority to extend the permitted period for extraction and restoration to 2 October 2026, Planning Application SDNP/16/04886/CNDC.
Novington Sand Pit has produced soft sand from the Folkestone Beds, mainly for use in mortar. Remaining sand reserves in the eastern part of the site are estimated to be 350,000 tonnes, representing about 9 years further extraction given prior constraints on the annual permitted tonnage.
Restoration to landscaped lakes for biodiversity and recreational use is required.
Consultation on this application closed on 13 January 2017. Sussex Wildlife Trust's submission notes that the site has been unused for about 4 years and is returning to nature so new biodiversity surveys should be carried out and the restoration plan reviewed. In the application the operator has failed to recognize the previously documented biodiversity and geodiversity of the site. East Chiltington Parish Council has objected on similar grounds, while Plumpton Parish Council opposes further stop-start sand extraction.
On 27 January 2017 planning permission was granted for extending the period for extraction and restoration until October 2026 subject to the same operational and environmental constraints as previously approved.
January 2017 - Worthing College Geology Evening Classes for BEGINNERS, Winter Term 2017

December 2016 - Update for Heath End Sand Pit
The planning application SDNP/14/00111/CND by Dudman Group for permission to continue sand extraction until the end of 2018 was refused in March 2015. After continued extraction at the site the South Downs National Park Authority issued an enforcement notice in August 2015 to close operations at the site.
At a subsequent appeal hearing in June and July 2016 two appeals were considered:
Appeal A against the original refusal of planning permission was dismissed.
Appeal B against the enforcement notice was allowed. The enforcement was quashed and planning permission was given for continued sand extraction until the end of 2021 subject to new conditions.
On 5 December 2016 Dudman Group applied for discharge of condition 4 of the planning permission with supporting documents detailing their proposals for the dealing with the various issues covered by this condition (SDNP/16/06089/DCOND).
A proposed method for the future working and extraction across the site is presented. With the exception of the northern-most area, where the current processing plant area is located, the remaining permitted reserves lie beneath the current lake area. The extraction of the remaining reserves beneath the lake will be undertaken using a dredger. The dredger will use a GPS positioning system to ensure efficient underwater extraction and underwater surveys will check lake bed levels.
The proposed programme for restoration and aftercare of the site is the main item of interest for geodiversity and biodiversity.
The central feature of the restored site will be a lake, landscaped and managed for conservation and “low key” amenity. Most of the lake will be retained as open water with reed beds along the northern shore. Around the lake restoration will comprise conservation grassland together with drifts of woodland and shrubs and two exposed sand faces.
The exposed sand faces on the eastern and southern banks of the lake will provide habitat for sand martins and also expose the geology of the Folkestone Beds for future educational and research purposes. These retained faces will be engineered to be stable and about 4m in height.
A report is presented to assess the impact of further extraction of sand on the stability of the Duncton Common round barrow cemetery, a scheduled archaeological monument. Based on the assumptions made, the analyses show that the overall stability of the final slopes is acceptable but the construction of the slopes must be carefully monitored to avoid any over extraction.
This article updates the original report posted in September 2015 here.
November 2016 - Marked increase in erosion of Sussex chalk cliffs in past 150 years
Research led by the British Geological Survey has revealed a 10-fold increase in retreat of chalk cliffs in East Sussex during the past 150 years. The studies, carried out at Beachy Head and Hope Gap, are based on measurements of beryllium-10 in flint nodules exposed in the wavecut platform. This shows how long the nodules have been exposed to cosmic radiation at the surface.
Over a period of 7000 years the cliff retreat seems to have averaged 2.5cm per year at Hope Gap and 6cm per year at Beachy Head. This compares with 20-30cm per year recorded for the past 150 years based on topographic maps and aerial photography.
The acceleration in retreat may be partly due to thinning of the gravel beaches which otherwise would protect the foot of the cliffs from erosion.

October 2016 - Brain tissue discovered in Sussex dinosaur fossil
Bexhill in East Sussex is well known for its dinosaur fossils, particularly those found in the Weald Clay at Ashdown Brickworks.
However a dinosaur fossil found by an amateur fossil collector on a beach near Bexhill in 2004 has made headlines recently. The fossil is a cast of a dinosaur's brain cavity probably from a relative of Iguanodon.
Researchers who have studied the fossil at Cambridge University now believe that it shows a thin veneer of mineralised brain tissues on its surface. This would be the first evidence of fossilised dinosaur brain tissue and it is astonishing that such delicate tissues could have been preserved for 130 million years.
July 2016 - Dinosaurs of Horsham: art, reality and fun:
A new temporary exhibition at Horsham Museum
9th July to 5th September 2016
176 years ago, there was a keen amateur fossil hunter who, looking over lumps of stone waiting to be cut to build a new chapel for Horsham, saw a dark mass amongst greyish brown rock, which proved to be fossil bones. Little did George Bax Holmes realise that his discovery of these bones of the dinosaur Iguanodon would catapult him in to the world of The Great Exhibition of 1851 or inspire video artist Toby Tatum 170 years later.
30 years ago a keen amateur fossil hunter looked at a mass of grey clay at Rudgwick Brickworks and saw lumps of dark stone. Sylvia Standing rescued the material, which also proved to be dinosaur bones, before it was to be made into bricks. Little did she realise that after 30 years of research these dinosaur bones would be identified as a new genus by Dr William Blows and named Horshamosaurus rudgwickensis after her home town and that of George Bax Homes or that the Friends of the Horsham Museum would then commission the world’s leading dinosaur artist John Sibbick to recreate our dinosaur.
Both fascinating stories and resultant artwork along with fossils remains are told and featured in the new temporary exhibition Dinosaurs of Horsham – art, reality and fun at Horsham District Council's Horsham Museum from 9 July to 5 September 2016.
The Wealden clay and sandstones in the area around Horsham have been known for their dinosaur fossils since the 1820s when the first bones of Iguanodon were discovered. Subsequent discoveries led to 'dino-mania'. In Horsham, respected Quaker George Bax Holmes became interested in such fossils and geology. Around 1837 he seems to have collected his first fossil, then three years later he found further remains amongst the building material for a new chapel in the town: these bones became known as the Great Horsham Iguanodon. Thanks to a loan by Brighton & Hove City Council's Booth museum, Horsham museum can display some of these amazing fossils. The size of them meant that the remains became the model for a large replica that was unveiled in 1854 at the world's first theme park, Crystal Palace, after the Great Exhibition, together with replicas of other dinsoaurs. At the time understanding of dinosaurs was in its infancy so the replicas are somewhat fanciful. They still stand there today in Crystal Palace Park.
In the early 1980s, Horsham museum volunteer Sylvia Standing led a small group to Rudgwick to rescue some fossils found in brick clay. The remains caught the eye of polymath Dr William Blows, who, in his spare time has spent years researching dinosaurs belonging to the genus Polacanthus. The fossils found at Rudgwick looked similar, but were different, and after further research they were assigned to a new genus Horshamosaurus. In the Victorian era, they transformed fossils into 3D sculptures; for Horshamosaurus, the Friends of Horsham Museum have commissioned the world's leading dinosaur artist, John Sibbick, to re-create the dinosaur in a painting so that we can see what it looked like.
As well as displaying fossil remains, the exhibition Dinosaurs of Horsham also showcases the work of Reading born video artist Toby Tatum, who has produced a short film Monsters. It features Horsham's Iguanodon along with the other dinosaur sculptures in the Crystal Palace Park. Toby has exhibited the film around the world at various film festivals and now thanks to the support of Toovey's Fine Art Valuers and Auctioneers the Museum is delighted to be able to show it in Horsham. It is the first time that video art has been shown in the museum and adds a different dimension to what will be an amazing multi-layered exhibition which tells the story of dinosaur discoveries and artistic interpretations.
The museum is also delighted to be able to display Dinographica Britannica, a new work by French artist Adrien Sina who on New Year's day 2016 visited Crystal Palace Park, and captured the spirit of these amazing Victorian creations including the Great Horsham Iguanodon by skilfully blending these photographic images with those found in drawings of fossils from Sir Richard Owen's History of British Fossil reptiles. It adds amazing views to an exhibition that reflects the Victorian passion for modern technology looking at the past.
A range of dinosaur summer fun sessions will complement the exhibition and a children's dinosaur themed trail around the museum will help keep the children entertained during the holidays. For more information on the children's activities see www.horshammuseum.org/whats-on.
Dinosaurs of Horsham - art, reality and fun opens on 9 July and runs until 5 September 2016. The exhibition is multi-layered with elements that will appeal to all those interested in dinosaurs, art, scientific history, Victorian skulduggery and a lot more besides. This amazing exhibition would not have been possible without the support of the Washington based auctioneers and valuers, Toovey's.
Horsham Museum & Art Gallery is open Monday-Saturday 10am – 5pm. Free Admission. For more information: www.horshammuseum.org
June 2016 - Cocking Chalk Pit site visit:
As part of the restoration plan for Cocking Chalk Pit the South Downs National Park Authority are considering the potential for long-term management of the site to preserve geological exposures and provide access to them in conjunction with management for biodiversity. A site visit was arranged for 25th May to allow members of the Sussex Geodiversity Partnership to demonstrate the educational value of this quarry. The SDNPA was represented by local rangers Ian McConnell and Sam Buckland and the SGP by Rory Mortimore, David Bone and Peter Anderton.
This is one of the few pits exposing a Chalk section of mid-Turonian age. We started in the upper part of the quarry where the lower New Pit Chalk is well exposed and finished in the lower part where the upper Holywell Nodular Chalk is also well exposed. Most of the section is easily accessible from benches and the large quantities of debris at the foot of each bench provide plenty of material for close examination. Rory’s nephew Josh Shearing took GPS reading at key points which could be included in a geological trail.
Rory gave us a guided tour and showed how wide the educational opportunities are for this site. The Holywell and New Pit chalks each have their own distinctive physical properties and were quarried for different uses. Fractures in each chalk unit are distinctive. Some marl and flint layers are also present and act as marker horizons traceable over large distances from southern England to eastern Europe.
Fossil assemblages change from the base to the top of the section reflecting evolutionary and environmental changes. Chalk was deposited in a marine environment where seas were more acidic and shows abundance of sponges rather than corals. This may be relevant to modern ocean environments under global warming.
The landscape of the South Downs reflects the varying properties of the underlying Chalk formations. The properties of the Holywell and New Pit chalks determine the shape of the main escarpment of the South Downs. The Cocking wind gap and dry valleys visible to the west of the pit raise questions about their origin during the Quaternary period.
The site is easily accessible with safe areas for viewing the geology and examining rocks and is suitable for groups from primary school age to Sixth Form and university. It would also be a good site for demonstrating the physical properties of the chalk units to engineers and geotechnicians engaged in large construction projects.
Ideally the restoration of the quarry should leave the geological exposures and benches available for permitted access via a marked geological trail. Rory has sent a report to the SDNPA proposing a geological trail for Cocking Chalk Pit.
May 2016 - Just published – Guide to Bracklesham and Selsey:
The geology and fossils of Bracklesham and Selsey
This new and well illustrated guide provides an excellent introduction to the geology and fossils of Bracklesham and Selsey based on David Bone’s extensive experience and knowledge of the area. It replaces his 2009 guide to Fossil Hunting at Bracklesham and Selsey. Since 2009 major coastal changes have resulted from the Environment Agency’s scheme breaching the shingle beach at Medmerry and the new coastal defences at Bunn Leisure holiday camp and the new guide takes these changes into account.
Most of the guide is focused on the geology of the Bracklesham Beds of Eocene age with their wide variety of fossils but there is also space devoted to Quaternary deposits in the area. David offers practical advice on where and how to hunt for fossils along Bracklesham Bay together with general advice of collecting fossils. Space is also devoted to other geological finds along the beach and to aspects of coastal erosion.
This guide should be an essential reference for anyone interested in fossil hunting along Bracklesham Bay or wishing to appreciate the geological history of the area.
The book costs £4.00 and is available from the Novium Museum, Chichester or by post from David (extra £1.30 p&p at cost). His address is 4 Kensington Road, Chichester PO19 7XR and his email is email@example.com.
April 2016 - Cocking Chalk Pit Restoration Plan:
The South Downs National Park Planning Authority has received a restoration plan for Cocking Chalk Pit from the landowners, The Cowdray estate.
The plan allows for natural regeneration, which should be a positive thing from a bio-diversity and landscape perspective.
This report proposes a restoration plan for the Cocking Chalk Pit using the methodology of natural recolonisation. The plan is to create a species-rich calcareous grassland site characterised by grasses and herbs dominant in a chalk downland landscape. The plan considers the various existing uses of the site other than mineral working, as well as the need to preserve the historic geology now evident from the previous workings of the chalk pit.
The Cocking Chalk Pit restoration plan can be downloaded here (2.82MB) .
The SDNPA would welcome any comments on this plan.
Their contact is Chris Fairbrother, Landscape Strategy Lead
February 2016 - Into the Wealden:
On February 17 to 19 2016 three Belgian researchers (two archaeologists, Sibrecht Reniere from University of Ghent and Aurélie Thiébaux from University of Liège , and one geologist, Roland Dreesen from University of Ghent) visited West Sussex.
Both archaeologists are actually working on a PhD that focuses on Roman stone tools in Gallia Belgica and Germania Inferior: whetstones, millstones, quern stones, ointment palettes, etc. One of the aims is to determine geological and geographical provenances. These can inform us on distribution patterns and the Gallo-Roman socio-economics. For the geological aspect of the research they have the petrographical support of several geologists.
The visit had one main goal: learning more about the provenance of Roman whetstones made from a very distinct imported sedimentary rock, found on Belgian and French archaeological sites. Based on the research results of Prof. Allen (University of Reading) flaggy calcareous sandstones of the Wealden Clay formation are suspected as most probable geological sources. The first day of our stay we discussed the subject with Prof. Allen and had a look at several thin sections of British samples. These were petrographically compared with thin sections from our Belgian archaeological samples. The second day the aim was to have a look at some outcrops and locate potential geological sources in the western Weald area. Without the help of the local geologists, this would have been impossible. Gill Woodhatch, David Bone and Peter Anderton accompanied us during our visit to the Horsham Stone and Reclamation site in Broadbridge Heath where we could take samples from the typical Horsham stone. Later on they guided us through the local landscape to show us a Wealden sandstone outcrop, the Okehurst Sandstone at Coppedhall Hanger. After a nice lunch where cross-channel contacts were forged, we visited some historical buildings in the surroundings to have a look at a variety of local quarried and used building stones. Some of them showed a potential good match with our "Wealden sandstones".
Unfortunately we didn't find any outcrops that could be the ultimate source for the production of the Roman whetstones. With 30 or more lenticular sandstone beds in the Weald Clay formation, it is like searching for a needle in a haystack. Nevertheless we learned more about the local landscape and the geological potential for an important whetstone production during Roman times. Even more important, we got to know some people who share the same passion: geological and archaeological heritage. To be continued.
Finally we want to thank Gill (Horsham Geological Field Club), and David and Peter (Sussex Geodiversity Partnership) for their hospitality. Without their support and guidance our stay would have been far more difficult and less productive.

January 2016 - Charmandean Quarry update:
In 2014 Southern Water proposed to use the site for an Aquifer Storage and Recovery (ASR) project.
A pilot borehole was planned for 2015 but is now postponed until problems with site remediation can be resolved (January 2016).
Southern Water ASR leaflet can be downloaded here (211kB) .
December 2015 - Horton Clay Pit Pleistocene deposits:
Although the Gault Clay SSSI at the eastern edge of Horton Clay Pit will be buried during the final stage of landfilling of the former pit, the site retains significant geological interest because of the Pleistocene deposits overlying the Gault Clay at its western edge.
These deposits appear to record the progressive infilling of a channel of the River Adur marking a transition from relatively cool climatic conditions to the onset of cold periglacial conditions. This sequence, unique in Sussex, has yielded a rich fossil assemblage, ranging from large herbivores to beetles and pollen, providing evidence of the environmental changes.
A description of the deposits and the history of excavation has been prepared by Dr Matt Pope, UCL Institute of Archaeology and can be downloaded here (87kB) .
In November 2015 a site meeting was arranged between the site manager (Viridor), Matt Pope and Peter Anderton (Sussex Geodiversity Partnership) to see how development of the site since 2000 has affected the deposits and to assess the possibilities for further investigations. A central area between the angling pond and the site office appears to be still intact and available for further work, so provisional agreement has been reached for ground clearance and exploratory coring in spring 2016 and possible excavations later in the year.
October 2015 - Update for Newtimber Chalk Quarry:
In March 2013 the operators submitted an application for a periodic review of minerals planning permission allowing chalk extraction until 2042. This was approved by the South Downs National Park Planning Authority in January 2014 (SDNP/13/02439/ROMP).
The approval is subject to a number of conditions including submission of a fully detailed landscape restoration and aftercare scheme for the site. This was submitted in April 2015. The scheme proposes 5 phases of restoration up to 2042.
The restored landform will be created by progressively cutting 5 to 10 m individual high faces each separated by 5 m wide benches. The design gradient is shallow enough to accommodate and limit degradation processes likely to cause retreat of faces at crest until stability equilibrium is established.
To ensure their suitability for general amenity afteruse for nature conservation and landscape purposes, any necessary stabilisation of the worked out chalk faces will be carried out...
The working and restoration of the site will be carried out in accordance with the sequence of Phased Working Scheme... (see drawings)
September 2015 - Current status of Heath End Sand Pit:
The quarry is in the final stages of sand extraction and the operators Dudman Group had permission to extract sand until the end of 2013.
In December 2013 Dudman Group applied to the South Downs national Park Authority for permission to continue sand extraction until the end of 2018, Planning Application SDNP/14/00111/CND.
This application was refused in March 2015 for the following reasons:
- The applicant had not demonstrated how much sand reserves remain and how they would be worked and processed on site.
- The applicant had failed to demonstrate that the proposed development would not adversely impact on the Duncton Common Round Barrow Cemetery, a Scheduled Ancient Monument.
This decision is currently subject to appeal which started in June 2015.
After cessation of sand extraction the owners are required to restore the site for biodiversity and recreational use.
September 2015 - Proposed infilling of Rock Common Sand Quarry:
The quarry is in the final stages of sand extraction and the landowner, Wiston Estate, and the quarry operator, Dudman Group are considering plans for infilling the site.
In their December 2014 Newsletter the Washington Parish Council asked resident to have their say on the future of Rock Common Quarry and register their interest in being invited to attend a community workshop.
In the July 2015 Newsletter the council reported that a meeting was called by Dudman Group with the Wiston Estate to discuss the future of the sand pit. The meeting was well attended. However the problems with the future of the pit and the adjoining Windmill Quarry site are still unresolved.
Two reports in the County Times in March and April aired local residents’ concerns about proposed plans for infilling the site. The local community are opposed to this and would like to see the site become a nature reserve or home to an environmentally based project.
September 2015 - Horshamosaurus - a new British dinosaur:
Our August news item on Rudgwick Brickworks mentioned the most famous fossil found there, the dinosaur Polacanthus rudgwickensis.
However, following a reassessment of the fossil material, Polacanthus rudgwickensis has been placed in the newly erected genus Horshamosaurus.
September 2015 - Development of Keymer Tileworks site:
In 2010 Croudace Homes Ltd and Keymer Tiles Ltd were granted outline planning permission by Mid Sussex District Council to develop the site for housing. One of the conditions for approval was the requirement to arrange for palaeontological recording during the site investigations and associated earthworks.
Planning application 09/03697/OUT can be viewed on the Mid Sussex District Council website: pa.midsussex.gov.uk/online-applications
Clay extraction ceased in 2013 but the factory continued to operate until 2014 using the stockpiles of material on site.
A proposal from the Natural History Museum for geological and palaeontological recording during the site excavations was approved in 2014. This aims to mitigate the loss of geological and palaeontological interests following development of the site.
|Loss of Lower Weald Clay clays, silts and sandstones (central area of works)||GPS locality recording in site report, excavation and retention of bulk samples|
|Loss of Upper Weald Clay sandstone (southwest area of works)||Retention of section in Conservation area (see map)|
|Loss of boundary sequence showing contact between Lower and Upper Weald Clay (southwest area of works)||Retention of section in Conservation area (see map)|
|Loss of fossil rich vertebrate microsites in Lower Weald Clay (central area of works)||GPS locality recording in site report, excavation and retention of bulk samples. Processing of samples for specimen recovery|
|Loss of fossil rich invertebrate and plant horizons in Lower Weald Clay (southwest area of works)||Retention of section in Conservation area (see map). Collecting during site investigation. Processing of samples for specimen recovery|
This proposal can be viewed on the Mid Sussex District Council website under planning application 09/03697/DCOND
Croudace submitted planning application for Phase 1 of the development in August 2014. Phase 1 covers the factory site only. This application 14/02830/REM can be viewed on the Mid Sussex District Council website.
September 2015 - Geology Photographic Competition 2015:
As you may know, the Geologists’ Association is running a photographic competition this year which is open to anyone and we are keen to receive as many entries as possible. It is a great opportunity for imaginative photography!
All the entries will be put on display at the Festival of Geology, University College London on 7 November 2015 and there are impressive cash prizes!
Entries will also be considered for inclusion in the 2016 GA Calendar which will this year be on sale at the Festival of Geology (full credit will be given).
August 2015 - The Threat to Water Lane, Hampshire:
Water Lane is an historic hollow lane linking West Worldham and Alton cutting 20ft down into the Upper Greensand Formation. Its historic interest is linked to its geological interest as mentioned by Gilbert White in his world-famous classic work The Natural History and Antiquities of Selborne 1789. It is a route that that he routinely travelled along on his way to Alton.
For the most part the site is effectively a stream or gorge. This is especially so to the north, downstream, where water runs along the base of the lane and there are banks either side up to four metres in height. The stream runs along bedrock in the northern section and the bedrock is often exposed up the sides of the banks as well.
Water Lane is already a Site of Importance for Nature Conservation (SINC) at county level for its old woodland indicator species of plants, microclimate, ferns. It is a wildlife corridor. Malmstone in moist pockets of these lanes is also a substratum for interesting mosses.
Most of lane is cut in Upper Greensand Formation with varying lithology from malmstone in the south to blue rag in the central section. Blue rag is a hard siltstone which forms the floor of the lane. There are very few exposures of blue rag in the area. Towards the northern end sides are less rocky as the more shallow part of the hollow lane cuts through the West Melbury Marly Chalk Formation.
The importance of retaining the Lane in its original state
- The Upper Greensand Formation is nationally limited to the western Weald and Wessex while the blue rag is even more local. The latter was used by Gilbert White’s grandfather for the Selborne village street in the early eighteenth century.
- There are very few exposures of malmstone and especially blue rag left that are safely accessible and not at the side of a busy road with cars.
- The rocky hollow lanes through the malmstone give excellent views of the lithology and processes of geography but most of them have been surfaced with tarmac and incorporated into the modern highway network. As Water Lane was replaced by a new road (B3006) in mid 19th century it continues to provide a walkway and shows the lane floor as it was in earlier times, with both historical and aesthetic interests.
- Whilst there are other hollow lanes in the Lower Greensand Formation of the western Weald e.g. around Haslemere, Surrey they are of an acid iron-rich sandstone, a different lithology with different flora and fauna compared with the Upper Greensand Hollow lanes.
- A special feature of Water Lane is the hydrology and its effect on the rocks, flora and fauna. Arable fields on the malmstone bench give rise to surface run-off and there are also spouts into the lanes from bedding planes and the aquitard effect of the blue rag. In winter there is running water down slope for the whole section but especially so from a tributary gully. This water enters the Caker Stream, part of the Wey catchment. One does not want imported rock with different lithology affecting the water chemistry. Also it is valuable to keep the accessible teaching opportunity for demonstrating processes of erosion by water.
The lane is classified as a BOAT (Byway Open to All Traffic) and is part of a planned new trail, The Writers’ Way. As part of countryside access work to upgrade the BOAT as part of The Writers’ Way Hampshire County Council have started to cover up the natural bedrock and put in drainage pipes. As the work involves a natural water course, as well as placing foreign rock material obscuring the local geology and potentially affecting water chemistry to the Caker Stream, Ordinary Watercourse Consent is required under the Flood and Water Management Act 2010. Works have therefore been stopped for the time being.
Hampshire Biodiversity Information Centre (HBIC) recently requested geological advice from the Sussex Geodiversity Partnership to determine whether the Water Lane site should be designated as a Regionally Important Geological Site (RIGS), also known as Local Geological Sites. On 25th July David Bone and Dr Peter Anderton representing Sussex Geodiversity Partnership joined Nicky Court (HBIC) and Dr June Chatfield to inspect the site. The weather was very favourable, a fine day after heavy rain, so the watercourse over the Blue Rag siltstone could be observed with significant water flow. The contrast between the natural bed of the lane to the north and the upgraded section to the south was very evident. Cherty sandstone aggregate from the Hythe Beds of the Lower Greensand used to upgrade the lane has buried the natural malmstone and is very different in colour and composition.
The concensus after the visit confirmed that the site clearly met the criteria for designation as a RIGS (or LGS). Documentation is now in progress.
August 2015 - Restoration of Rudgwick Brickworks claypit:
Rudgwick Brickworks claypit was closed in 2012 and the site was subsequently sold.
In April 2015 a waste planning application to West Sussex County Council for restoration of the site by infilling the pit was approved subject to conditions which include some recognition of the site’s geodiversity value as a Local Geological Site (RIGS).
The application reference number is WSCC/38/14/RW and relevant documents can be downloaded from the planning website.
Details were provided in a report to the planning committee in October 2014.
Planning Committee Agenda Item No. 4 (174kB)
Edited extracts from report:
from Executive Summary:
This report concerns a proposal by R Harrison & Sons to restore Rudgwick Brickworks, a former claypit. Restoration would involve the use of 622,500 tonnes (415,000m3) of inert wastes/materials over a period of four years. 590,100 tonnes (393,400m3) of restoration material would be imported by road, to be used along with extracted materials/wastes already on site, which will form the balance of the total amount of material. Restoration of the claypit would enable the future use of the site as grazing land for the applicant’s dairy herd alongside the adjacent Woodsomes Farm estate.
The proposed development, when restored, would result in a landform similar to that prior to clay extraction but containing significant improvements in terms of benefits to the wider landscape and in terms of agricultural afteruse and benefit within the locality. Existing mature planting adjoining the claypit would be retained and protected.
from Site and Description:
2.11 There are no statutory landscape, ecological or historic designations within the site. The southern and eastern areas of the site are designated as a Regionally Important Geological Site (RIGS), considered to be of regional importance for geodiversity. The site is not within an area identified as being at increased risk of flooding. It is not within a groundwater source protection area. The Brickworks itself is recorded within the County Council’s ‘Sites and Monuments Records’.
from Relevant Planning History:
3.6 The site and adjacent brickworks were most recently operated (from 2006) by Wienerberger but production became unviable and both clay extraction and brick production ceased in 2012.
from Final Restoration:
The proposed final landform aims to reinstate the original contours of the surrounding land prior to clay extraction..........Existing clay and overburden stockpiles on site would be graded back and incorporated within the overall phased restoration scheme along with the imported materials.
4.19 The final landform would have slopes not exceeding gradients of 1:12 to allow for modern agricultural operations to be carried out. It would have open fields enclosed with trees and hedgerows, as well as new woodland planting and a hedge between (north of) the former brickworks and restored claypit.
4.20 Surface water would be managed through the creation of ditches running to new and existing ponds on the western and southern boundaries of the site. An area of clay would remain exposed in the north-eastern corner of the site for future geological study relating to the site’s designation as a RIGS.
Edited extracts from Decision Notice (31/03/2015)
The planning application was granted subject to a number of conditions which are specified in the decision notice.
Under the heading of Landscaping, Restoration and Aftercare Scheme the approval requires that:
The development hereby permitted shall not take place until landscaping, restoration and aftercare details have been submitted to and approved in advance and in writing by the County Planning Authority.
To be included in this submission is the following item:
(e) The measures, including mitigatory works, to be taken to protect and incorporate the site’s exiting and historic features of archaeological, ecological and geological interest into the restoration scheme and how such features would be managed in the long term following completion of the restoration.
Wealden Field Meeting - Rudgwick and Clockhouse brickworks

July 2015 - Proposals for reuse of Shoreham Cement Works Beeding Quarry:
Recently proposals have been put forward for reuse of the former Shoreham Cement Works and quarry, Upper Beeding. This chalk quarry is designated as a Local Geological Site (former RIGS) which does not have the statutory protection of a Site of Special Scientific Interest. It is a very large quarry with excellent exposures of the Lewes Chalk and Seaford Chalk formations and is currently leased to Dudman Group for recycling of building waste. It is encouraging that the site is not being proposed for landfill.
A number of earlier proposals to reuse the site have been unsuccessful. However the current proposals appear to be based on wider consultation and community involvement and are innovative. At this time the plans are at a conceptual stage but it seems worth following their progress to identify opportunities to provide input to any future planning application review.
The Beeding Quarry is considerably larger than the former Bodelva Quarry which houses the Eden Project in Cornwall so it has the potential to host a major tourist attraction. It certainly has enough space to allow industrial heritage, geodiversity and biodiversity preservation alongside proposed business, leisure and cultural activities.
Meanwhile in May 2015 Dudman Group applied to the South Downs Park Authority for renewal of permission for the importation, storage and treatment of inert material to produce recycled/secondary aggregates until 31st October 2019. This can be accessed online at southdowns.gov.uk/online-applications

Draft Cement Works Policy V5
Posted December 2014
There is no specific mention of geodiversity in the policy but there is potential for its inclusion within the overall framework.
Edited extracts from the draft policy that seem compatible with preservation of geodiversity
Beeding Cement Works, Upper Beeding
The Cement Works is of great public interest and is part of the history of Upper Beeding when it was the major employer and source of income in the area. In a recent survey within the Parish 76% identified that the Cement Works was a major issue and needed something to be done to it.
The Upper Beeding Neighbourhood Plan wishes to identify opportunities for development and employment at the site as part of a regeneration and restoration package for the Cement Works. Any proposal for development must deliver the principal objective of securing the satisfactory restoration of the site with major environmental and landscape improvements compatible with the site's sensitive location in an Area of Outstanding Natural Beauty within SDNP.
There are opportunities for development and such sites have been transformed from industrial to recreational and business use very effectively while retaining the industrial features of interest and value.
A community museum could be created & funded from sponsorship to promote the re-generation of the site and allow access for schools and local societies to re-search and promote their local history and ongoing local environmental/wildlife conservation
Any development proposal must:
- be sustainable
- ensure that opportunities are maximised to enhance the landscape and biodiversity of the area whilst protecting the existing wildlife habitats.
- be a comprehensive scheme for the whole site.
- include development that is necessary to secure the satisfactory restoration of the site.
- represent the optimal viable use of a heritage asset
- have the support and backing of the local community
- provide the community access to open spaces, social, cultural and educational benefits, well-being and inspiration from interaction with nature supported by a strong healthy economy.
Ideas for Beeding Cement Works from Community Engagement
- Build South Downs Visitor Centre with parks, camp site, shops, cafe, Youth hostel, stables, and cycle centre.
- Bus Museum and Artefacts Cement Works Museum & Heritage Centre
- Wild Life Centre and Sanctuary for birds, fish & plants. Utilising the river.
- Local Tourist attraction.
An imaginative proposal to develop the site has been produced by the Upper Beeding community as described in Upper Beeding Parish Council Newsletter for March/Spring 2015.
As you know we carried out a questionnaire back in 2014 asking people for their key issues and 74% said they would like to see something done to the Cement Works Site rather than it being left as an eyesore and blot on the countryside in SDNP. Having visited the site owner Hargreaves, Dudmans (who have an option to buy) and the SDNP (the Planning Authority) it seemed pretty clear that nothing was going to happen for another 20 years unless we tried to do something about it. All did say they liked some of our ideas but.......... So with the help of some willing professionals Bill Dunster (Architect), Alex Hole (Business Strategy & Planning) and Mat Bulba (Project Manager, Director of The Low Carbon Trust & Blooming Futures - Green Fuels) turned the community's ideas into some innovative proposals that can be properly funded. Since then we have presented to Coast to Capital (Enterprise Board), SDNP and circulated the proposals to Horsham & Adur District Councils and WSCC who have all supported and liked the ideas. We have presented again to the SDNP Executive & Members and are waiting their views on what they might permit being developed on the site.
It is quite clear that the proposals formed from a lot of ideas from the Community and approved in principle by the UB Parish Council are very different to those being proposed by Hargreaves but are by no means set in stone. A lot depends on who and how much we can get to invest. Once we get some indication from SDNP on their intentions we will hopefully be in a position to hold some public meetings in the Parish to present the proposals more widely and get feedback.
The community proposal can be seen on the parish website as a slide presentation:
from Executive Summary
The Off Grid Project was formed as a positive response to a series of negative proposals put forward for The Shoreham Cement Works site - one of the biggest brown field sites in the South East situated in the Heart of the South Downs national Park. Working with and Building on the local Parishes neighbourhood plan - A team of experienced Architects, Project Managers and Financial Advisers have put together a regeneration master plan that will meet the needs of the local community while enhancing the Public experience of the National Park. Set against the current global need to cut carbon emissions the project will offer the chance to experience low impact living first hand - The heart of the project gives visitors to the National Park a chance to sample a snapshot of a zero carbon / zero waste future that is fun and actually works well. The proposal will bring new life and employment opportunities into the area within a vibrant zero energy development containing an entertainment venue for open air performance. Our proposal uses landscaped terraces to repair an industrial scar on this cherished part of the countryside. We will sensitively create desirable holiday accommodation within a vaulted amphitheatre that can host the worlds leading musicians and performers. We will return plants and wildlife to this degraded environment and generate all running power from on-site renewable energy. The iconic industrial buildings will be retained, renovated and enhanced with the addition of a translucent solar roof. Our proposal will safeguard existing jobs and create new employment that responds to the unique context of the national park. By providing a new cultural offer it will create an exciting new role model for developments in the national park.
The proposal is supported by a large number of images and plans which demonstrate the imaginative scope of the project.
July 2015 - Proposals for reuse of Chantry Mill Quarry:
Recently proposals have been put forward for reuse of the currently inactive Chantry Mill Quarry, designated as a geological SSSI, a GCR site and a Local Geological Site (former RIGS). The proposals are encouraging because they appear to provide for preservation of part of the quarry for its geodiversity value as well as adding value for biodiversity. Usually sites like this seem destined for landfill. At this time the proposals are at a conceptual stage but it seems worth watching this space for opportunities to provide input to any future planning application.
In the proposed Storrington, Sullington and Washington pre-submission Neighbourhood Plan (April 2015) there is support for re-use of the currently inactive Chantry Mill Quarry for tourism or other community related development, provided that:
(Edited Extract from page 33 of the Neighbourhood Plan)
- The development scheme has full regard to the provisions of the West Sussex Local Minerals Plan and to the approved restoration scheme of the minerals workings;
- The design and access of the scheme will conserve the landscape and scenic beauty of the South Downs National Park;
- The scheme proposes a green infrastructure masterplan that makes provision for preserving, restoring and recreating habitats of the adjoining Chantry Mill Site of Special Scientific Interest and that includes proposals for landscaping and ecological connectivity with the surrounding land;
- The scheme prevents harm to the geological conservation interest of the quarry;
- Significant harm resulting from the development is avoided or is adequately mitigated or, as a last resort, compensated for;
- The scheme makes provision to mitigate the cumulative impact of new traffic movements of the scheme and of the proposals for Chantry Mill Industrial Estate; and
- The economic, social and tourism benefits arising from the scheme can clearly outweigh any adverse environmental impacts.
(Extract from page 34 of the Neighbourhood Plan)
4.52 The proposals for the former Chantry Mill Quarry relate to only that part of the larger site. They are intended to encourage the reuse of the site for a new tourist attraction for the area, which again complements the Core Strategy and HDPF tourism policies and Policy 2v of the SSWNP, which allocates the adjoining industrial estate for employment and housing uses. They acknowledge the safeguarding of potential future minerals deposits (as defined by the West Sussex Local Minerals Plan) and the provisions of the conditions for the restoration of the quarry workings. The policy also requires proposals to take into account the designation of part of the wider site, but not the developable area, as an SSSI and its location within the setting of the National Park.
(Extract from page 25 of the Draft Sustainability Appraisal/Strategic Environmental Assessment)
7.19 The proposals for tourism development (Policy 7) are divided into three parts. The first two parts offer qualified support for proposals to reuse former and current minerals workings for tourism and community facilities. Given neither proposal is that well developed at present, the policy falls short of allocating the land for these purposes. However, it is known that both sites – Chantry Mill Quarry and the area forming the Sandgate Country Park – have a range of biodiversity value (most notably the Chantry Mill SSSI) as well as some potential landscape (National Park) and heritage (the Chantry Mill heritage asset) value. Though both proposals are intended to deliver strong economic (7A) and/or social benefits (2A), the policy qualifies its support for these proposals in such a way as to ensure planning applications satisfactorily address any potential conflicts with biodiversity (3A), the National Park setting (4A) and heritage (5B) policy objectives. As both proposals relate to the beneficial reuse of minerals workings, the policy acknowledges the requirements of those proposals to accord with approved restoration conditions and the wider policy provisions of the West Sussex Minerals Local Plan.
The Neighbourhood Plan (Draft Plan and Supporting Documents) can be accessed online at:
Also accessible from the home page this website is a proposal from Dudman Group, the current owners of Chantry Mill Quarry, for the redevelopment of Chantry Industrial Estate and Chantry Sand Quarry.
Chantry Industrial Estate and Chantry Sand Quarry proposed redevelopment
Chantry Down and Chantry Campus
Chantry Sand Quarry (approx. 14.8 hectares – 36.64 acres) restoration with the associated costs of stabilising work would be met by the proposals, utilising the quarry bowl, protecting the quarry floor and natural habitat with almost no visual impact. The scheme will provide increased employment and would be a unique ‘landmark campus development.’
The proposed uses for the quarry area have wide and varied possibilities, all of which would be using this resource in a positive and innovative way. Commercial, institutional, health, educational or leisure uses – or a mix – could all play a part in these imaginative ideas.
The scheme provides for new and existing natural landscaping, improved access, parking, public open space and attenuation ponds while retaining mature woodland (which has current permission for removal). They alleviate the threat of traditional landfill use and importing a major volume of materials for quarry restoration after further sand extraction.
Sand Quarry Existing Use: Quarry has permitted use and is still a viable working sand quarry with demand re-emerging however the continued working has the owner operators’ conscious landscape impact concerns.
Quarry & Restoration: The Quarry requires restoration upon completion and much consideration will need to be given to all of the adjoining properties including the Sussex Down (former RAFA) Residential Care Home, less than 6 - 10 metres from the Quarry edge. There is continual vermin and weather erosion to the quarry edges. Traffic management will need to be considered fully to allow all these works to take place and a new access may need to be considered as beneficial. In years past, normally a site with such large volume area would have been considered for Landfill. However the proposals alleviate the threat of Landfill use and the need also for the import of a major volume of inert materials for the whole of the quarry restoration after any further sand extraction.
Proposed Sand Quarry site design: this will allow a development providing a unique ‘Campus’ environment, suitable for relocated local businesses with the opportunity for incoming new businesses or an institutional or educational campus for primary and/or secondary education could be considered, all of which will provide employment. The proposals will encompass elements of the vernacular in the residential design with modern amphitheatre design, using minimal ground space while stabilising the quarry walls.
The Campus allows for an amphitheatre design, with the double effect of the ‘design and build’ construction to stabilise the sheer quarry walls for the long term and complete restoration but leaving the quarry floor with sympathetic contours and water management systems.
Landscape: proposed developments do not impinge on landscape or views and the development is taking up the sides of the quarry rather than building on the quarry floor. It is proposed part of the quarry sides will remain once the total site has been made safe for natural habitat.
- Mature Woodland: The proposals allow for the mature woodland which under current permissions to the South West boundary, would be removed in the normal course of sand extraction will remain and new planting increased throughout.
Geodiversity: the conservation of part of the Quarry will provide safe access to continue geological features for ongoing sampling and study and to allow for site after-use which includes geodiversity objectives for education and heritage.
Biodiversity: the proposal will allow existing flora and fauna and natural habitats in the Quarry to continue and expand.

May 2015 - Horton Clay Pit local geological site to be infilled:
Due to rain infiltration and slope slippage of the soft Gault Clay this site has become unstable and its condition has been assessed by Natural England as Unfavourable-Declining. Natural England does not consider that long-term remediation is possible. Consequently the site will be buried and infilled with waste conformable with the adjacent existing landfill which occupies most of the former clay pit.
Viridor’s proposal to infill the site was summarised in a newsletter to local residents in 2014:
Planning permission for the infilling was given by West Sussex County Council on 4 November 2014:
(work has not yet commenced – May 2015)
- minor excavation of the surface of the clay to allow final inspection and recording;
- the placement of a marker horizon of chalk (or similar material) against the clay slope to allow it to be located again in the future if necessary;
- progressive infilling the remainder of the void by imported materials to stabilise the face and reduce water ingress;
- installation of markers at the new ground level to identify where the underlying exposure can be found; and
- restoration planting and seeding to improve the range of habitats provided for the completed landfill restoration.
Burial will preserve the geology but restrict access in the future.
December 2014 - A Museum for The Etches Collection at Kimmeridge:
It was long thought that the Kimmeridge Clays had little to yield by way of well-preserved fossils. This belief was changed by the amazing discoveries of Steve Etches, a fossil collector and expert local to Kimmeridge, who over the past 30 years has discovered, collected and researched over 2000 incredible Late Jurassic Kimmeridgian specimens. This is an achievement that has resulted in a collection of the most extensive and finest fossil specimens ever found in the Kimmeridge Clay Formation.
Many of the species Steve has discovered are new to science and are of great palaeontological importance. Each find has been perfectly curated, providing an immaculate record that reveals every aspect and tells the stories of these incredible creatures from deep time, how they bred, how they lived and died.
Limited space means that the collection is not currently housed together and viewing can only be made by appointment. In 2008 the Kimmeridge community formed a collaborative Trust. Their objective is to provide a secure and permanent home for The Etches Collection, making it readily accessible to all and conserving it as a national treasure. In early 2013, the owner of the Smedmore Estate gifted land on which to build a museum. Steve also gifted his priceless collection to the Trust.
Plans are well advanced to create a unique museum for The Etches Collection based in Kimmeridge, especially designed to give an engaging and educational experience with which the local community can also be fully involved. It will be a place that will become a major attraction to the many visitors that frequent the village and Kimmeridge Bay each year as well as a variety of new audiences.
Visitors will enter the Exhibition Gallery and be taken on an immersive journey through life underwater 150 million years ago. The ceiling space will be transformed into an aquarium of the past delivered by CGI projection. Below, the fossil collection will be showcased in illuminated cabinets. The specimens will be carefully presented and interpreted to bring to life their individual stories.
The museum will also include an educational and research area and a visible workshop enabling the careful extraction and preparation process to take place so that the collection can continue to develop and expand.
The delivery and construction plan is underway and is set to achieve completion and opening of the museum in early 2016.
Find out more about the project and follow its progress on the website: www.theetchescollection.org
The project has already received substantial financial support to build the museum but will need continuing support and sponsorship to maintain the facilities and develop the educational and research programmes.

November 2014 - GEOLOGICAL CONSERVATION REVIEW
The Geological Conservation Review (GCR) is a milestone in geo-conservation. The GCR identified sites, of national and international importance, that demonstrate the key elements of Earth History within Great Britain. The GCR forms the basis of statutory geo-conservation in Great Britain; a site must be a GCR site before it can be considered for protection as a Site of Special Scientific Interest (SSSI).
The scientific description of each GCR site is being published in a series of GCR volumes incorporating the insights and expertise of generations of leading geologists. Some 34 volumes were published by the Joint Nature Conservation Committee (web-site: http://jncc.defra.gov.uk/page-2731); many more were planned. In 2011 the Geologists’ Association took over publication of further volumes through Special issues of the Proceedings of the Geologists’ Association (PGA).
Essentially, each volume provides exceptional reviews of current knowledge, plus a series of geological site descriptions (extremely useful to assist field excursions). Three Special Issues have been published in the PGA and others are planned during the next few years. Also, it is intended that descriptions of any new GCR sites to emerge will be published in the PGA.
Electronic PDF files of chapters within the Special Issue GCR volumes are available via the PGA website; in addition hardback and softback copies of these Special issues can be purchased (on-line) from Elsevier our publication partner. A “how-to-do-it flyer” from Elsevier is attached to this note.
The following volumes are available for purchase in hardback or soft back.
- The Marine Devonian of Great Britain (PGA Volume 122, Issue 4, 2011)
- The Non-marine Lower Cretaceous Wealden Strata of Southern England (PGA Volume 123, Issue 2, 2012)
- The Dalradian Rocks of Scotland (PGA Volume 124, Issues 1-2, 2013)
We expect to publish the following volumes during the next two years:
- Quaternary of East Anglia and the Midlands
- Quaternary of Southern England
- The Jurassic-Cretaceous Transition in Southern England
Further volumes are expected once these are completed.

October 2014 - Logging the Chalk, Rory N. Mortimore:
Chalk has proved to be one of the more difficult rocks to core-log as it breaks up readily during the drilling process leading to core-loss and destructuring, particularly where flints, nodular chalks and/or fractures are present. One of the greatest difficulties is the identification of chalk engineering grade which relies heavily on fracture aperture. Obtaining the correct grade to define the depth of weathering and the depth at which fractures become closed is essential whether for tunnels in London or for wind turbine piled foundations in the offshore chalks. Very few geologists and engineers have had the opportunity to study field sections in the Chalk so there is little visual appreciation of the grades or the variation to expect or even what flint bands look like. To partly overcome this difficulty, both field and core sections are illustrated in this book. Equally important to recognising Chalk grade is the building of conceptual ground models for construction projects. This can only be achieved if the various Chalk formations, beds and marker beds can be identified from cores and then boreholes correlated using the marker beds. The Chalk stratigraphy is accordingly covered with key formations and marker beds illustrated, and the best field sections for viewing them identified. This book is based on the standard lithostratigraphy and method of engineering description of Chalk developed over many years. Also important are over 3000 onshore and offshore chalk-cored boreholes undertaken by the author over more than 30 years. In addition, typical lithologies and weathering profiles representing the Chalk formations likely to be encountered in the various onshore and offshore construction projects are illustrated using field exposures, rotary core samples and geophysical borehole wire-line logs. There will be geological settings where information on the Chalk is poor and unexpected lithologies and stratigraphies may be found. This book will enable geologists to work from first principles to construct a lithostratigraphy and define weathering boundaries.
5 Star Customer Review:
As a geotechnical engineer based in the south-east of England (particularly London), there are several soil and rock units that I encounter frequently; The Lambeth Group, Thanet Sand, London Clay and Chalk. Chalk is one of the harder units to log for several reasons. Assigning strata boundaries in the chalk can be tough because at first glance the chalk can appear uniform (it is not). Recovery in chalk core can be pretty poor and often a geology degree or eurocode logging course will not cover chalk specifics that are essential for proper detailed logging of the chalk.
This book is (and will be) regarded as the chalk logging bible for any engineering geologist/ geotechnical engineer who encounters chalk in the field as a logging engineer or for people reviewing written logs back in the office. Its steep price genuinely reflects the quality of material within. Of particular use is the large colour annotated photographs of the kinds of things that I could encounter while logging (trace fossils, marker beds, marl seams, various flint types etc). Often core photographs are laid out next to graphic logs of the same sequence as an example of how chalk core can appear in the field.
For those who encounter the chalk in the field, this is the ultimate reference book. Rory Mortimore has visited many ground investigation sites over his career and this is the book people like me have been asking him to write for years.

February 2014 - Large crack appears along cliff top at Birling Gap:
A BBC report on 27 February shows a large crack that has recently appeared at the cliff top at Birling Gap following the recent cliff falls in January due to the severe winter storms. (http://www.bbc.co.uk/news/uk-england-sussex-26373624).
January 2014 - Reported cliff fall at Birling Gap:
Average rate of erosion of the Sussex Heritage Coast chalk cliffs is ~1m/year; in reality, after years of no erosion, along comes a big one, often due to winter freeze-thaw, though this time it ws down to the total saturation of the cliffs battered by the severe storms. (http://www.bbc.co.uk/news/uk-england-sussex-25603539).
January 2014 - Hastings cliff collapse:
The recent series of severe storms battering the south coast will undoubtedly be reshaping the cliffs and foreshore to a significant extent.
A spectacular cliff collapse at Rock-a-Nore, Hastings on 3rd January was captured by camera and shown on BBC News (http://www.bbc.co.uk/news/uk-25604696).
The collapse is located in the Foul Ness Local Geological Site and a photo taken in 2011 showing the pre-collapse state of the cliffs at this location is shown as photo 2 in the site description for Foul Ness. The event highlights the instability of these cliffs where thick massive sandstones overlie a sequence of weaker siltstones and thinner sandstones.
September 2013 - Ice Age erratics discovered at Medmerry, Selsey:
The Environment Agency's Medmerry Managed Coastal Realignment scheme on the Selsey peninsula has been completed this autumn (2013), some 5 years after being formally proposed. Around 6.7 km of new flood embankments have been constructed to protect 300 properties and several large holiday caravan sites from coastal erosion and rising sea levels for the next 100 years (Photo 1). The existing shingle bank around Bracklesham Bay has been cut through to enable high tides to inundate the low-lying pasture and fields of the Earnley and Medmerry areas. Shallow lakes formed by the flooding of borrow pits and new drainage channels will assist in the creation of new saltmarsh and natural habitat that will be managed by the RSPB. For more information on the scheme, see http://www.environment-agency.gov.uk/homeandleisure/floods/109062.aspx
About 2 km of foreshore around Bracklesham Bay will be affected by the gradual retreat (probably over decades) of the existing shingle bank that will no longer be maintained by the Environment Agency. This foreshore falls within the area designated as a geological Site of Special Scientific Interest for its Palaeogene and Quaternary geology. Every effort has been made to minimise damage to the SSSI area during construction of rock groynes and other works associated with the scheme, so any impact on the foreshore outcrop and existing geological exposures will only become apparent as the impact of high tides and storms gradually rolls back the shingle bank towards the new flood embankments.
Some interesting geological features have appeared during excavation of the borrow pits and new drainage channels, some of which cut through Quaternary raised beach deposits. Of particular note was the discovery of several large erratic boulders of non-local rocks such as granites (Photo 2). Although these are found around the coast and occasionally from inland excavations, the Medmerry scheme revealed a number of these boulders in situ and also enabled a comprehensive collection of a large suite of rock types to be made from an abundance of smaller examples.
The erratics range from boulders a metre or more in diameter down to cobble-size specimens. The rocks are believed to originate from Brittany or the Channel Islands, where similar rock types occur, and were ice-rafted across the English Channel during the Ice Age – but a lot more research still needs to be carried out. Three large boulders have been saved to form a future educational feature on the site (location to be decided), but the largest is currently located by the visitor centre at the nearby Pagham Harbour Local Nature Reserve on the road to Selsey (Photo 3).
August 2013 - Fracking:
"Fracking" or to give it its technical name hydraulic fracturing is currently very much in the news nationally and in Sussex with the test drilling by Cuadrilla at Balcombe.
Hydraulic fracturing has been used offshore for many years for improving the recovery of gas and oil from conventional sandstone reservoirs which have low permeability (so-called "tight" reservoirs). Water under high pressure is injected into the rock to generate open fractures which allow the oil and gas to flow more freely to the well bore.
The present controversy and debate is about the use of hydraulic fracturing onshore for the extraction of gas and oil from shale rocks. Shales are essentially impermeable and the oil and gas contained in them can only be produced via the open fractures generated by hydraulic fracturing. Unlike conventional oil and gas reservoirs, which are localised, the shale reservoirs occur over wide areas and produce for relatively shorter times so that many more wells need to be drilled.
Apart from the termporary site disturbance associated with all drilling and production activities several other environmental issues have been identified with hydraulic fracturing. These include the potential for groundwater and surface water pollution, the local demand for large quantities of injection water and the potential triggering of earth tremors.
