Can anyone help?

Plymouth City Museum and Art Gallery are currently undertaking a large project on a collection previously owned by Sir John St. Aubyn, the 5th Baronet (1758 to 1839). Currently, there is much interest in the missing’ elements of the mineral collection and the journey to their respective resting places. After his death, Sir John St. Aubyn’s collection was split by the mineral dealer Isaiah Deck (1792-1853), and although an extensive collection was arranged for the Civil Military Library at Devonport (now at the main Plymouth City Museum), the remaining minerals were auctioned.
As part of the project, Plymouth City Museum and Art Gallery are trying to locate other specimens from Sir John’s mineral collection. The wish is to authenticate and photograph every specimen both in the museum and in other collections so that an online digital database can be created. If you can help, please contact the Natural History St. Aubyn project assistant, 01752 034774 - www.plymouthmuseum.gov.uk

December 4th - Birds and Dinosaurs with Feathers

On Thursday December 4th, Prof. Mike Benton from the University of Bristol will be talking on 'Preservation of the birds and dinosaurs with feathers from Liaoning China'. The lecture starts at 7.30 at 16 Queen Square and is organised by the Bath Geological Society.
There was a sensation ten years ago when the first photographs of fossil birds and dinosaurs from the Early Cretaceous of Liaoning in China were published. Here were exquisitely preserved specimens that showed feathers. Other fossils were also exceptionally well preserved. The most astonishing find was that a number of small carnivorous dinosaurs too had feathers, so confirming the long-standing view that birds evolved directly from dinosaurs. A team from the University of Bristol is working with colleagues in Beijing to study the preservation and tissue structure of the feathers. We hope to understand just why so many thousands of astonishing specimens have been so well preserved, and to find what the unexpected view of soft tissues tells us about the evolution of birds.

Rock specimens needing a good home

A geologist's collection needs a good home! The specimens are mostly rock samples; many have been purchased so they have names with them. Others have parted company with their labels so
just need matching up. There are 4 - 5 carrier bags full.
Email contact if you are interested.

Cornwall in April

Cornwall with the Oxford Geology Group in April.
Click here to view the preliminary programme, which fills a week.
The idea would be to spend most of the day in the field, in various ways, including hiking, studying landforms and geology close-up and at least one day collecting minerals and/or rock samples.
There are also a number of good geological guides, two of which are mentioned in the programme.
So far one lodge that sleeps six at Lanteglos has been booked (click here). At present they have ample accommodation and, depending on interest, we may book more.
We intend to use our own cars as transport.
Contact the Oxford Geology Group if you are interested.

Note the date: November 6th - Climate change in permafrost regions

Professor Charles Harris, Emeritus Professor of Geology at Cardiff University, will be giving this talk for the Bath Geological Society on Thursday November 6th at 7.15 p.m. at BRLSI, 16 Queen Square, Bath.
'The impact of climate change on slope stability in permafrost regions'

Permafrost is continuously frozen ground, and is widespread in the high arctic, becoming thinner and discontinuous further south. It may also underlie the higher peaks in mountain regions. Thawing of frozen ice-rich soils leads to thaw settlement and major loss of strength, often leading to landslides. On steep bedrock slopes, ice-bonded joints may increase rock mass strength, so that warming and thaw increases the risk of rock falls and rockslides. Thus, permafrost regions are particularly sensitive to climate change, and engineering works must incorporate measures to accommodate this. Evidence for recent warming in permafrost regions will first be presented, and its significance with regard to future trends discussed. Examples of the impact of permafrost degradation on steep bedrock mountain slopes will then be presented, with evidence drawn largely from the Alps. Finally, the response of soil-covered permafrost slopes to climate warming will be considered through field studies in Canada, Svalbard and Norway, and through laboratory modelling experiments.
Everyone is welcome - members are free, £4 for visitors. Do come along and join our very active Society. Details of some of next year's exciting events can be viewed on our website.

Free event - British Geological Survey

The British Geological Survey is running its fourth free annual event for the public, at Keyworth, Nottinghamshire, in support of the National Archives Awareness Campaign, on Saturday, 29th November 2008, and is providing tours of its Records Centre, Materials Collections, Library, Enquiry services, and 3D Visualisation Suite. The Dando drilling rig will also be demonstrated.
The national theme is 'Community Participation' and the tours will follow a geological time line highlighting the conditions on the Earth through various times and the geology we see today. We have selected local industries in the Midlands that have exploited this resource e.g. road stone, gypsum, coal, ironstone, etc. and will demonstrate how these uses have developed and changed over time. We will highlight the records and archives we hold , show how they are of increasing value today, particularly in respect to the geohazards and past exploitation and how we supply information of value to communities today, through the services we provide.
Booking is via our website and it is aimed to appeal to all the family.
There are also free BGS tours on Professionals Day - Friday November 28th - booking is required.

The Last Glaciers of the Brecon Beacons

Interested? Then do come along to 16 Queen Square, Bath on Thursday October 2nd at 7.30 to hear this talk by Dr. Rick Shakesby from Swansea University.
The higher parts of the Brecon Beacons National Park, South Wales, represent the most southerly area of the UK that had glaciers during the final, relatively brief cold phase (known as the Younger Dryas or Loch Lomond Stadial) of the last glacial cycle. This phase lasted only about 1,400 years from about 12,900 to 11,500 years ago, after which there was an abrupt change of climate to the comparatively warm conditions of the Holocene, which have continued until today. It appears that conditions in the Brecon Beacons only allowed very small glaciers to exist at the bases of steep escarpments where copious quantities of wind-drifted snow could accumulate. Evidence for the existence of these glaciers comprises some impressively large, steep-sided moraines and moraine complexes that appear to be almost as fresh today as when they were deposited so many thousands of years ago. Not everyone has accepted either the period of formation or a glacial origin for these scarp-foot depositional landforms. The talk will be illustrated with examples of the landforms and will consider some of the past and current debate concerning their origins, together with the climatic implications for this last occasion when climate was radically different from what we experience today.

Oxford University Museum of Natural History

A date for your diary – Sunday October 12th. Dr Monica Price, Acting Director of the Oxford University Museum of Natural History is treating us to a special visit:-
- Behind the scenes visit to look at the Mineral Collections
- The Corsi collection of decorative stones
- New Fossil and rock displays opened last year
- New gemstone display
The Museum houses Oxford University's extensive world wide collection of zoology, entomology, geology and mineralogy, including the local dinosaur finds, a 40ft (9m) Tyrannosaurus rex, the observation beehive and Alice's Dodo. The building itself is one of the finest examples of the Victorian Gothic style of architecture, exhibiting a wealth of naturalist carving: the huge glass roof over the central museum court is supported by cast iron shafts, decorated with wrought iron spandrels.
This is a follow-up to Dr Price’s lecture on 'Marbles and other Decorative Stones' in April 2007 and her kind invitation to visit the museum. Meet at 10.30 a.m. at the Museum. Park and Ride recommended. Packed lunches or eat at one of the local pubs. Please note that the Pitt Rivers Museum is closed at the moment for building work.

Fancy a trip to Edinburgh?

Fancy a trip to Edinburgh? Stuart Monro, WEGA's Horstmann Lecturer of 2007, and Scientific Director of Dynamic Earth in Edinburgh, has agreed to show us the Geological Sights.
At the moment the programme is -
1. Meet at Dynamic Earth on the morning of Saturday 25th October for a tour of the Dynamic Earth galleries under the guidance of Stuart.
2. After lunch, a geological excursion round Arthur's Seat. This is an ancient volcano which abuts Dynamic Earth. This will be led by Stuart and will include the section where Hutton proved the intrusive nature of igneous rocks.
3. On Sunday morning, 26th October, an excursion to a nearby locality - maybe North Berwick or Dunbar and, hopefully, by public transport.
The best bet for transport seems to be Easyjet. You can get to Edinburgh and back again for £88 (including most of the "extras"). National Express coaches take about 12 hours and cost about £70. The train takes the strain for £131.
There is a wide variety of accommodation in Edinburgh, varying from the cheap and cheerful to the luxurious. Google Edinburgh Accommodation and make your choice. Remember that there are more than geological reasons for visiting the Scottish Capital. Your partner may want to visit the galleries or the shops or take in a concert or theatre on the Saturday evening. It is not necessary to attend all that I have arranged with Stuart.
Contact WEGA if you are interested

No Curator of Geology at Bristol Museum??

Did you realise that no geological curator has been appointed since the departure of Dr. Tim Ewin, despite the fact that Bristol’s geological collection is the sixth largest Museum collection in Britain?
Until now, the Museum has had a specialist Geology Curator for about 180 years. Bristol’s excellence in the preparation and display of fossil vertebrates has continued down to the present day. This is acknowledged internationally. Accessions include one of the most complete Pliosaurs ever discovered, the oldest Stegosaur ever discovered, and, recently, the best preserved dinosaur (Scelidosaurus - photo) ever found in Britain. The Geology galleries are amongst the top three visitor attractions in the Museum and the material includes several National Heritage collections.
For the first time in almost two centuries, Bristol is currently without a specialist Geology Curator. Not only does the curator look after the collection but is a source of geological expertise for the public.

Lady required by WEGA - sorry gentlemen

A female person has pulled out of WEGA's trip to Northumberland. Would you be interested in filling the gap?
The dates are Saturday 13th September to Saturday 20th September 2008. It would cost £550 for the week. You would be sharing a twin-bedded room with some other lady in a hotel where we will be staying on a dinner, bed and breakfast basis. Click here for details of the hotel. The £550 includes the hotel, transport in a superior minibus, including from and to Bristol, and tuition by Andrew Bell, a well known Open University lecturer.
The geology is also rather superior - mainly Carboniferous but lots of other stuff, including (at a small additional expense) a boat trip to see Siccar Point - the most important unconformity in the world!
If you could give a response soon WEGA would be very grateful - email

Tedbury Camp - latest information

This is to let you know that a new website describing Tedbury Camp, near Frome, is now available. Over the last couple of years this wonderful locality has attracted the documentation it deserves and there are now three major complementary sources of information available for the area.
The new website -
'Tedbury Camp - a geological gem in the Mendip Hills', has been compiled by Dr. Martin Whiteley on behalf of the Earth Science Teachers' Association (ESTA). It is aimed at A Level students, undergraduates and researchers, and includes lots of illustrative material and a detailed map of the quarry. It forms part of the ESTA website.
The two other sources of information are:-
- the UKRIGS Earth Science On-Site education project which is designed to encourage non-specialist science teachers to undertake Earth science fieldwork with pupils from primary to GCSE level,
- British Geological Survey (2008) publication - walkers' guide to the geology and landscape of eastern Mendip. This can be obtained from the BGS at Keyworth, Nottingham for £12 and comprises a 68-page book and a map at 1:25000 scale. Additional information can be found on the BGS website.
In the future, we hope to improve the steep access path to Tedbury Camp, clear some of the overgrown faces and produce a geotrail leaflet that describes this and several other localities in the Mells valley. It will be aimed at casual visitors who may be interested to learn a little more about the rich heritage of this area.

Events in July

3rd July - The History and Hydrogeology of the Minor Spas of South West England. This talk is organised by Bath Geological Society and is to be given by Professor John Mather.
"From Elizabethan times onwards, wealthy people of rank travelled to centres such as Bath and Buxton to "take the waters". In addition to these large centres, a network of minor spas developed to provide for the middle and professional classes and for the poor. A number of small spas in Somerset and Dorset achieved brief fame in the following centuries for the medicinal properties of their waters. There was such a rush to Alford Spa, near Castle Cary, in the 1670s that there was insufficient water to serve all the patrons. Horwood Spa, near Wincanton, had its own bank in 1809 although the enterprise was bankrupt by 1819. Nottington Spa, near Weymouth, was described as 'the only pure sulphureous spa in England'. The history and geology of these and other minor spas will be described and the origin of the mineral waters discussed."

July 6th - following the talk - Trip to Malvern to look at the Hydrogeology of the various springs and the history of Hydropathy in Malvern - Meet at 10.00 a.m. at Great Malvern beneath the Abbey Gateway and the museum. Further details are on the website. Email or 'phone 01249 813628 to let us know you are coming.

July 6th - organised by WEGA - The industrial archaeology of the lead mining industry of the Mendips. We intend to look at Charterhouse and Velvet Bottom. In this area the industry has been in existence since at least Roman times - some say that the Romans invaded Britain to get control of the lead and silver mines. And mining continued into the early years of the twentieth century.
If you would like to attend this trip, contact WEGA via the website.

Fast forming mountain ranges

A member of WEGA has recommended this site - click here.
Mountain ranges are so big, and continental plates move so slowly, that common wisdom suggests they must take millions of years to form. This seems to have been confirmed in the past with limited data sets that show the timing of their uplift; however, a recent paper in Science and another in Earth and Planetary Science Letters have suggested that uplift may occur much more rapidly in some cases.

New 'East Mendip Study Centre'

This fantastic new centre will replace the Mendip Quarry Producers' East Mendip Study Centre at Hanson's Whatley Quarry. It is an architect-designed, single storey building next to Wainwright's Moon's Hill Quarry at Stoke St. Michael. It is a carbon neutral building with its own wind-powered generator and a high thermal mass. It includes traditional and sustainable construction materials and is sited alongside former quarry workings which have been restored into a lake and nature reserve.
It has been funded principally by the Somerset Minerals Forum, Somerset County Council's aggregates levy sustainability fund and the Mendip Quarry Producers (MQP), a trade association representing all the major quarrying companies in Somerset.

June 5th and 7th - Huntley Quarry and May Hill, Gloucestershire

'The Enigmatic Huntley Quarry' On June 5th, Hellen O'Connor, Gloucester Geology Trust, will give a talk to the Bath Geological Society about this quarry. For over 180 years geologists have been arguing over the date of the rocks of this very small quarry nestling in the side of May Hill. The quarry contains the only known exposure of the Huntley Quarry Beds. These volcaniclastic sediments, sandstones with volcanic material, have been subject to intense tectonic activity due to the close proximity of the regionally important Blaisdon Fault. This fault is very well displayed in the quarry as is the folding and distortion of the Huntley Quarry Beds themselves. Importantly, the age of the sediments is still unknown with a possible age range of 570 Ma (Precambrian, Neo-proterozoic) to 436 Ma (Silurian, Llandovery) having being postulated. The talk will discuss the sediments and the problems of dating them.
On June 7th, Hellen will lead a field trip to the quarry where the Huntley Quarry Beds and the Blaisdon Fault can be examined; there will also be an opportunity to see the newly exposed Lower Silurian Bright's Hill Quarry. Details can be found on the Bath Geological Society's website.
Everyone is welcome to attend these two events - non-members £3.00. Please contact the society on admin@bathgeolsoc.org.uk if you wish to come on the field trip but cannot come to the talk.

May 1st and May 3rd

Don't forget the Bath Geological Society's lecture this Thursday - 'The finest dinosaur ever found in Britain' by Dr. Tim Ewin, acting Curator of Geology, Bristol City Museum and Art Gallery.
After a cliff fall in 2000 on the beach at Black Ven near Charmouth, Dorset, professional collector David Sole made the discovery of a lifetime. He found the partial remains of a Scelidosaur that turned out to be the finest dinosaur specimen ever found in Britain. Dubbed the Horned Scelidosaur this spectacular, 3-metre (9 foot) specimen has a devilish grin, magnificent body armour and even the contents of its last meal preserved.
Dr Tim Ewin, currently curating a display on the Horned Scelidosaur, will introduce these spectacular British dinosaurs and the world they inhabited and describe the remains of the finest dinosaur ever discovered in Britain.
Scelidosaurs were heavily armoured, quadrapedal, herbivorous dinosaurs the size of a small car that roamed the lush tropical world of the Lower Jurassic some 190 million years ago. This dinosaur specimen will be on public displayed from Spring 2008 in the Dinosaur Gallery at the Bristol City Museum and Art Gallery.

Saturday May 3rd - Tim Ewin is leading a tour around the Museum to further illustrate his talk. Please contact admin@bathgeolsoc.org.uk if you wish to be included on this visit.

Bristol Science Cafe

Did you know about this? The Bristol Science Cafe is at Tobacco Factory, Raleigh Road, Southville, Bristol BS3 1TF. It meets on the last Monday of each month at 8.00 p.m. Directions can be found on its website.
April 28th - The speaker is Adam Durant from the Department of Earth Sciences, University of Bristol. His topic is: Volcanoes, dust, and climate.
Small silicate particles suspended in the atmosphere redistribute energy from the sun and surface of the Earth and consequently impact climate. The main sources of these particles are from suspension of surface dust in arid regions, such as the Sahara Desert, and from direct injection by explosive volcanic activity (volcanic ash). The image shown here is from 1991 Pinatubo eruption and shows a volcanic aerosol veil, taken from the space shuttle.
We will discuss the types and origin of particles in the atmosphere, how they interact with solar and terrestrial radiation, how clouds are modified, and ultimately how climate is affected.

April 26th Geology of the Ledbury Hills

This field trip is organised by the Bath Geological Society and will be led by Dave Green, an expert on the area. Dave writes "We will explore the geological history of these beautiful unspoilt hills, largely composed of sedimentary rocks of Silurian age, thrown into folds by the mid to late Carboniferous tectonic movements which formed the Hercynian or Variscan mountain belt between the supercontinents of Laurussia and Gondwana. The geology is faithfully reflected in the scenery, composed of alternating layers of resistant and non-resistant rock, many of which are rich in fossils, which in the case of the lithologically non-diverse Ludlovian have been the method for dividing the sequence into rock units. Large-scale diversion of drainage took place during the Pleistocene with the production and overflow of a pro-glacial lake."
Meet at 10.30 a.m at the large car park at British Camp (G.R. SO 764403). There will be a fairly strenuous climb to the top of the Herefordshire Beacon, if the weather is clear, to gain an overall view of the area, followed by visits to various sites where rocks and structures can be examined.
Strong footwear and waterproofs are required. Bring packed lunch, or it can be purchased at the car park.
Please email the field excursion secretary - admin@bathgeolsoc.org.uk - to add your name to the list.

The image shown here is a 3D view of the geological maps of the Malvern Hills and Ledbury area. It was sent by a colleague from Wootton Bassett and has been produced using OziExplorer3D software. When used 'live' the terrain can be spun around, zoomed in and out and shadows altered.

Geomap for the Forest of Dean

The Forest of Dean Local History Society has been awarded a grant to create a unique Geomap sculpture of the area. The strata of the Forest will be represented by the actual rock types, taken from both working and disused quarries. The flat sculpture will cover 84 square metres and, although the surface will be polished, it will be rough enough for people to walk on safely.
The Geomap is intended to demonstrate and celebrate the link between geology of the Forest of Dean and its long quarrying and mining history. It will be built on a site called New Fancy on a flat, grassy area opposite the Miners' Memorial

In memory of Dr. Colin Parsons

I record with sadness the death of Dr Colin Parsons, who passed away peacefully on Tuesday 4th March, succumbing to the motor neurone disease which had been gaining the better of him for two years. Colin will be well known to workers on the Inferior Oolite formation from the many papers he published through the 1970s, working out the succession of ammonites in great detail, often from pits he painstakingly excavated by hand specially for the purpose. His comprehensive work covered the whole outcrop from the Dorset Coast, through Somerset and Yorkshire to the Isle of Skye, including re-determinations of many fossils and collections which had not been re-examined since the days of Buckman. After retreating from publication for almost thirty years due to his teaching commitments, he was embarking once more in retirement on a body of research. This included work in progress on the deposits at Dundry Hill and in north Dorset, benefiting from the assistance of mechanical plant for the excavations, but still applying his trademark meticulous observation, and contributing all the material to national academic collections.
I accompanied him on a number of his 'digs' and recall a kindly man whose immense knowledge never overshadowed his affable personality. He will be very much missed. Arrangements are in hand to publish obituaries in the Proceedings of the Bristol Naturalists' Society and other major geological journals. Further details on his funeral, his life's work, and proposals for memorial activities may be obtained from his close friend and working colleague John Huxtable, Telephone 01823 259395, e-mail johnhuxtable@hotmail.com

Earthquake - Wednesday 27th February

Have you seen the press release posted by the British Geological Survey? The earthquake was magnitude 5.2 and occurred at only 5km depth. The epicentre was Market Rasen, Lincolnshire.
Preliminary data, seismogram and the map showing the location of the epicentre are already on the BGS website and the site will be updated as new data become available.

There is also a simple online questionnaire which anyone who felt the earthquake should fill in. The information helps BGS to compile contour maps of the felt effects (or intensity) of the event based on the European Macroseismic Scale, and is used to create hazard maps. So please fill in the questionnaire if you felt the earthquake (if you didn't, fill it in anyway, it takes even less time and that's useful information too) and encourage others to do so.

We felt it here, near Bath. The bed went up and down four or five times and a pheasant who roosts in a nearby tree screeched and must have fallen of his perch judging by the noise which followed.

Santorini - 10th - 24th June 2008

Santorini: living with a volcano
A Study Tour - Tuesday 10th to Tuesday 24th June 2008
Leader: Peter G Hardy BSc,PhD
University of Bristol; Department of Earth Sciences

There are a few places left on this fantastic tour - BOOK NOW!

Santorini is now a well-established tourist resort, but retains much original atmosphere and boasts the most dramatic and beautiful scenery and exceptionally friendly people. Combine this with fascinating insights into the heart of a volcano and the opportunity to wander through the streets twice as old as those of Pompeii, and this tour is sure to charm you.
This course will comprise the equivalent of around eleven full days of organised activities in which we shall walk considerable distances with stunning views, but at a gentle pace. There will be ample time to examine details, appreciate the views, study local life and to recuperate in shady tavernas! The emphasis of the course will be on the volcanic rocks and the resulting dramatic landforms. These will be studied in the context of their effect upon the life of the inhabitants, both past and present. We shall visit major and minor archaeological sites and examine the older local architecture, since this is so strongly influenced by the geological history of this largely volcanic island.
The price of the tour is £980 per person and includes -
- return flights Gatwick/Santorini
- transfer to and from hotel
- half board accommodation in twin room with private facilities
- airport taxes

Water Cycling in the Deep Earth - March 3rd

On Monday 3rd March, the University of Bristol has been lucky enough to be included in a lecture tour by the Mineralogical Society of America's distinguished lecturer, Dr Steve Jacobsen from the Department of Earth and Planetary Sciences, Northwestern University. His talk is designed to be accessible to a general audience, and you are welcome to come along.
13.00 hrs in the lecture theatre G25,
Department of Earth Sciences,
Wills Memorial Building University of Bristol

"Water Cycling in the Deep Earth:

Are the Oceans Just the Tip of the Iceberg?"
Earth is unique among the terrestrial planets in having liquid water on its surface. Water controls the character of biology and geology of the planet. Deep reservoirs of water incorporated as hydroxyl (OH-) into the solid silicate minerals of the mantle may contain the majority of the planet’s hydrogen and acted as buffers to maintain ocean volume and continental freeboard over geologic time.
Just two-tenths of one weight percent H2O in subducted oceanic crustal material and subsequently released to the hydrosphere is sufficient to recycle the total ocean volume about once in 4.6 billion years. It is possible that fluxes are several times this amount. Nominally anhydrous minerals of the transition zone (410-660 km depth) may serve as the largest internal reservoir. New and recent data on the effects of water on the physical properties of minerals indicates that hydration has a larger effect on seismic velocities than does temperature within their respective uncertainties.
This talk will explore how experimental studies are being used to constrain the effects of water on the physical properties of Earth materials at high pressures and temperatures, which may ultimately lead to seismological detection of water in the deep Earth. Experimental data, in concert with thermoelastic modelling may be used to interpret enigmatic S-wave velocity anomalies in the mantle reported from seismic tomography, such as the one recently detected beneath eastern North America.

If you would like to attend - just come along!
