Geology of the Salisbury Cathedral Close

The Wiltshire Geology Group has just produced a new  geological guide for an hour or so self-guided walk round the Salisbury Cathedral Close. It is in a 12 page concertina and laminated form to make it handy and waterproof to carry in the hand. It explores the local geology and how this is reflected in the materials used to construct this exquisite space within the heart of Salisbury.
It is priced at just £2 and available from the Cathedral and Museum shops and the Sarum Bookshop.

7th January - New Dinosaur discoveries

New Dinosaur discoveries
Ben Garrod
7 January 2016, 7.30pm—9pm
Free – donations welcome

New and astounding dinosaur fossils continue to be discovered across the globe, shedding ever more light on what dinosaurs were and how they lived.
Ben Garrod will discuss some of these new findings about animals which were dominant on land for about 135 million years from  the Triassic, through the Jurassic and into the Cretaceous geological periods. He will talk in particular about a recent titanosaur discovery that he’s been following as part of a BBC 1 programme. This has included him helping 3D scan the largest thigh bone he’s ever seen.
Please note, the lecture takes place at Tyndall Lecture Theatre, University of Bristol NOT Bristol Museum & Art Gallery. Parking can be difficult so please arrive an extra 15 minutes to allow plenty of time. Access on foot is via the Royal Fort entrance, along the path and to the left.

December 3rd - Geology of Anglesey

Bath Geological Society - December 3rd
The Geology of Anglesey

Dave Green, Geostudies
For years the geology of Anglesey has caused controversy amongst those studying its complex arrangement of seemingly unrelated fault blocks, particularly the status of the PreCambrian (or are they?) granites and gneisses, sedimentary extrusive sequence, blueschists, ophiolitic/deep ocean facies and melange. So complex that the very stratigraphy has been completely overhauled and re-interpreted twice during the last 100 years. In comparison, the thin and deformed unconformably overlying Lower Palaeozoic rocks are simple, as are the Upper Palaeozoic sediments, with their excellent environmental indicators. On a final note of controversy - why is Anglesey, composed largely of ancient, resistant rocks, so flat in comparison to the nearby mountains of Snowdonia? This talk and the field trip to follow, will attempt to outline the main elements of the geology of the island and the evidence that has produced such geological controversy.
This talk will be followed by a visit to Anglesey in 2016.

Royal award for volcanology research by the University of Bristol

The University of Bristol has been awarded the Queen’s Anniversary Prize for Higher Education – the highest accolade for any academic institution – in recognition of its world-leading research in volcanology. 

Researchers from the group played a key advisory role following the eruption of Eyjafjallajökull.  Volcanic hazards are now explicit in the UK National Risk Register and the risk to aviation has been significantly reduced; ash clouds are better understood, monitored and predicted due to the implementation of the group’s research findings.  Their free web tool, PlumeRise, which gives more accurate estimates of the amount of ash injected into the atmosphere during a volcanic eruption, is now used by numerous institutions worldwide.

 An illustration of Ornithomimus based on the findings of preserved tail feathers and soft tissue. While studying at the University of Alberta, a first-year palaeontology student stumbled across a surprisingly well-preserved dinosaur fossil, with its tail feathers and some soft tissue remarkably intact. This Ornithomimus ('bird mimic') dinosaur, existed in the Late Cretaceous period in what is now modern-day North America.

Rock clearance day at Saltford - 20th November

Rock clearance day at Saltford
Friday 20 November 
Meet: 10:30am at the clearance site. Finish at 4pm.
Simon Carpenter is organising a rock clearance day on Friday 20 November to clean up a late Triassic/White Lias site close to the Railway Path at Saltford ST 691668. The site will eventually be part of a new geology trail around the village and I need your help.
The rock outcrop occurs along the rim of the cutting and I need a team to help clear ivy and vegetation covering the current rock face as well as removing a substantial talus slope that covers and obscures the lower part of the exposure. It should be possible to complete this work in one day.
If you are interested (volunteer days can be real fun, especially if the weather is nice), please ring or email me to register your interest: 01373 474086 and/or simonccarpenter@gmail.com
You will need to bring a spade, thick work gloves, secateurs and or loppers - some extra tools will be available if you don't have any of your own.  Bring packed lunch or there is the Bird in Hand pub a short distance away.  Bring lots to drink and warm clothing, if it's cold. 
There is a regular bus service to Saltford (X39) from Bath and Bristol or the site can be reached by bicycle of walking.  There is some car parking near the River Avon at 'The Shallows' and the rock exposure can be reached from here by a short walk.  There will be signs placed on the railway path adjacent to the rock exposure so that you don't miss it.

Mystery object found on the Bath GS Manor Farm trip

The object above was found at Borrow Pit, Manor Farm, Aust - a Triassic mystery.  An expert's opinion is as follows:-
"My interpretation of this is that it lacks the symmetry and detail to be a fossil animal in its own right, though algal activity may have played a part in producing the lumps on the surface.  It has a slightly laminated appearance and I believe it to be a sedimentary accretion.  Whether it has a nucleus of any kind could only be resolved by sectioning and polishing it, but I did notice the tell-tale signs of pyrite decay products around the edge of the central lamina.
Pyrite is widespread in the Westbury Formation.  It exists as individual cubes, clusters (framboids) and granules, and is largely responsible for the bluish black colour of the sediment. It arose as a result of the reaction between iron hydroxide gels (these are excreted by algal blooms) and sulphur liberated by sulphur-reducing bacteria sourced from organic matter such as coprolites or decaying plant material. The effect of one of these FeS clusters (they only need to be a few microns in diameter) at the sediment/water interface is to create a patch wherein the pH of the pore seawater is considerably reduced in relation to its surroundings; an acid bubble, if you like. Trapped within the sediment, this can have the effect of attracting, dissolving and then precipitating any calcareous material suspended in the seawater.
Bear in mind that the environment at this time was in the process of changing from the brackish marine conditions of the first Upper Triassic incursion, to the fluvial channel conditions of the much more calcareous Cotham Member, and ultimately culminated in the lagoonal, nodular calcareous mudstone strings of the pre "White Lias"  After the desert conditions of the Keuper, things became more and more propitious for shelled marine life, so it sort of fed off itself and there would have been more and more calcareous material present in the water, starting from small beginnings. Rhythmic precipitation of this sort, discussed by Tony Hallam in about 1966 I think, responds to seasonal and even diurnal temperature and salinity changes and proceeds from small pea-sized "nummular" nodules to gradually bigger ones and finally coalescing into continuous beds. Hope this helps."
It certainly does, thank you!

A Bug’s Life: The role of micropalaeontology in industrial problem solving
Professor Malcolm Hart, Emeritus Professor of Micropalaeontology at the University of Plymouth
Micropalaeontology is the study of microscopic fossils and has been used extensively by the hydrocarbons industry for the stratigraphical correlation of rock successions (especially recovered in boreholes). In many quarrying or engineering projects stratigraphical “control” is also required and this will be explained using the site investigation for the Thames Barrier and the construction of the Channel Tunnel as the leading examples.

19th September - Aust Cliff and Manor Farm

Bath Geological Society
Saturday 19 September 2015
Aust Cliff and Manor Farm, South Gloucestershire
Leader: Simon Carpenter
This field trip visits two important Upper Triassic sites in South Gloucestershire representing arid coastal, shallow marine and lagoonal environments. There is an abundant marine fauna, particularly bivalves and the Westbury beds are renowned for their fish and reptile remains - particularly isolated teeth and bones. The National Grid will be undertaking repair works on their pylon during mid-September and removing talus from the Aust cliff section alongside the concrete causeway - so there may be some disruption to our visit. Simon will bring material from his own collection that he has found at both sites.
It may be muddy, so please bring boots. Packed lunch or optional pub visit (Boars Head, Aust). Bring hammers and collecting bags.
Meet 10:30a.m. at the old Aust ferry jetty (ST 564889).
There is some parking along the roadside close to this point.
Finish at 3:30pm. The route to Aust (M5) is very busy on a Saturday so leave plenty of time for your journey.

Bath Geological Society - CHANGES

Please note the following changes to our lecture and field trip programme
September 3rd
Geological evolution of N American cordillera
Dr Doug Robinson

The North American Cordilleran mountain chain runs N-S along western North America, and reaches up to ~ 500 km in width. The chain consists of a number of mountain ranges such as the Rocky Mountains and Coast Ranges, along with a variety of geological entities including the Basin and Range Province, Colorado plateau, Cascade volcanic arc, Columbia flood basalts and the Yellowstone plateau. These different regions record a remarkable geological evolution over a period greater than the entire Phanerozoic. This evolution records the change of the western coast from a passive margin, marking the breakup of the Rodinia supercontinent in the late Precambrian, to an active subducting margin culminating in the Larimide orogeny and the formation of the Cordilleran mountain belts. The Tertiary evolution marks the orogenic collapse phase, with the plate boundary between the Pacific and North American plates changing from a destructive margin to one involving the two transcurrent faults of the San Andreas and Queen Charlotte zones, separated by the remnant of the destructive margin that has given rise to the Cascades volcanic chain.

Ancient underwater volcanic range may explain why Australia and New Zealand separated

A chance discovery by an Australian scientific vessel searching for lobster larvae has uncovered a range of underwater volcanoes that have remained inactive, and unknown, for an estimated  50 million years.
While scanning the seabed more than 150 miles off the coast of Sydney, scientists found a cluster of volcanoes sitting three miles beneath the ocean’s surface. In all there were four extinct volcanoes, the largest nearly a mile wide and rising some 2,000ft above the sea floor.
The volcanoes, now calderas which form after the eruption when the land around them collapses, may reveal why Australia and New Zealand separated between 40 and 80 million years ago.

Significance of bizarre exteinct creature revealed

A bizarre extinct creature that has mystified scientists since its 500m-year fossil was first unearthed more than a century ago has finally revealed its teeth – placing it centre stage in the evolution of many complex life-forms living today.
Hallucigenia, which owes its name to its unworldly appearance, was so odd that scientists initially confused its top from its bottom and its head from its tail. However, a study has now unequivocally identified its mouth, complete with a fearsome ring of sharp teeth.
Researchers from the University of Cambridge have also identified a pair of simple eyes on Hallucigenia’s head and have determined that it was a close relative of the last common ancestor of everything from tiny velvet roundworms to huge lobsters.

July 4th - Black Mountain, western Brecon Beacons

Just a few places left on the coach for this exciting Bath Geological Society field trip to be led by one of our favourite leaders, Dr. Geraint Owen from Swansea University!
The coach is picking up as follows:-
7.55 am. Leave Keynsham Football Club
8.05 am. Leave Bath Newbridge Park and Ride
8.10 am Leave Bath Queens Square
8.30 am  Leave Box Pharmacy
10.45 am ETA Brynammom:
3.30 Anticipated Return
Please email the field secretary to book your place as soon as possible.
Cost £25
The Black Mountain (Mynydd Du) is the western part of the Brecon Beacons. It lies within the Fforest Fawr Geopark and the Brecon Beacons National Park and is traversed by the Beacons Way. The geology comprises gently southward-dipping Palaeozoic strata on the north side (“North Crop”) of the South Wales Coalfield, ranging in age from late Silurian to late Carboniferous. As befits its location within the National Park, the area is scenically attractive, with extensive views to the south over the industrialised South Wales Coalfield and to the north into rural mid Wales. Although outside the area of coal-bearing rocks, the area contains an important legacy of extractive industries and associated infrastructure.
Several sites will be visited and the ground conditions may be rough and wet underfoot in places. Bring warm, waterproof clothing and sturdy, waterproof footwear. Please bring a packed lunch. Safety helmets are advisable at one site.
Further details and suggested reading list are available on request from the Society.

Vallis Vale, de la Beche unconformity SSSI

Alan Holiday and a couple of others from the Dorset Group did some conservation work on the de la Beche site in Vallis Vale, near Frome.

As you can see they did an incredibly good job.
Alan writes that as they were there there were at least a dozen young people camping. They were curious as to what we were doing and had no idea about the geology or the significance of the site. It seems strange that there is no indication this is an SSSI and its geological importance so people might treat the site with more respect. Needless to say they cleared up a some rubbish.
Those of us who use the site are indebted to them; thank you all!

9th June - 24th July - Geology and Landscape of Gloucestershire and surroundings

Geology and Landscape of Gloucestershire and surroundings
A weekly field-based introductory course.
No previous knowledge of geology is assumed
Tuesday evenings 9th June to 21st July 2015
Gloucestershire is one of the most geologically diverse counties in Britain.
The aim of this field-based course is to take you towards an understanding of local scenery.  We will look at the components, the highly diverse rocks and their structure; and processes, weathering, slope forming and erosion which have combined to produce this equally varied landscape, the materials from which the scenery has been sculpted and the processes that have acted upon them since the area emerged from the sea 65 million years ago (about the same time that the dinosaurs became extinct).
No special equipment is necessary, apart from stout footwear and possibly waterproofs - although we will hopefully have six balmy  summer evenings! Meetings are held on Tuesdays each week, meeting at 7.00 pm, finishing at 9.00 pm or later (whenever the party feels in need of refreshment !!) at the following meeting points (see over)
Cost: £50 for 7 week course or £9 per session
For further details telephone Dave Green on 01594 860858 or email.

Box: landscape, rocks and fossils with Elizabeth Devon
14th June, 2.15 Selwyn Hall car park, Box.
The walk will start from the Selwyn Hall car park in Box. After a visit to the nearby Box Rock Circus, we will make our way to the River Bybrook and so to St. Thomas a Becket Church. We shall then walk through the village identifying rocks and fossils en route. We then proceed (slowly) up the sequence of rock types in the valley to Quarry Woods. The views are spectacular and the geology is very clear. In Quarry Woods we will consider the quarrying industry. From here, our walk will take us down over fields to the Millennium sculpture in Lacy Wood and then to the view point of Brunel's famous Box Tunnel. We shall return via footpaths to the recreation ground and so to the Selwyn Hall car park. If time allows, we shall then use the 'Climate through Time' poster to put what we have seen on the walk into perspective. Copies of the poster and a hand-out will be available.

11th & 12th July - Two independent field courses - South Malverns & Jurassic of Cotswolds

Dr. Nick Chidlaw is organising the following two courses; they are independent of each other: both courses can be attended, or either course, according to your particular interest / availability. 
Each course has a fee of £25.00 per person.
Contact Nick if you are interested in either or both.

THE SOUTH MALVERNS AND ADJACENT AREAS: a circular geological walk
Saturday 11th July 10.00 am – 5.00 pm.
The dramatic ridge of the Malvern Hills has attracted the curiosity of geologists and naturalists, and drawn walkers for generations. This field day will take you on a gently-paced, circular walk across part of the high south Malverns, and the lower ‘hogs back’ and scarp country to the west, Frequent stops will allow landforms, both near and distant, and their underlying geology to be explained, and rock exposures examined en route. A variety of igneous, sedimentary and metamorphic rocks will be studied of Late Precambrian and Silurian age, revealing a legacy from two major episodes of plate tectonic collision and intervening tropical coral-rich seas. The walk is approximately 4 miles long, and no prior knowledge of geology or the area is assumed.

JURASSIC CONTRASTS OF THE COTSWOLDS: muddy rift basin seas and clear limestone shoals 
Sunday 12th July 10.00 am – 5.00 pm
During the Jurassic period (c. 200 – 145 million years ago), the North Atlantic Ocean basin was only just beginning to open between what is now the United States and NW Africa, and had not yet done so from Newfoundland and Iberia northwards. This latter area, which included the British Isles, was characterised by unstable crustal tension within which the remainder of the ocean basin would eventually open. This unstable crust, overlain by shelf seas and islands, comprised a mosaic of rift basins, each with their own history of subsidence and eventual stabilisation. The area of crust that became the British Isles at this time lay about 40 degrees N and had a humid, sub-tropical climate.  The Cotswolds are located in one of these formerly-active rift basins, and are characterised by strata that indicate repeated rifting and infilling by mostly muddy sediments in the Early Jurassic, and much greater crustal stabilisation, when mostly clear very shallow waters and the deposition of limestones prevailed, in the Middle Jurassic. No prior knowledge of geology or the area is assumed.

  Tuffley Brickpit

Leckhampton Hill Quarries

For each course, a handout outlining the day’s programme, including location sketch maps, optional reading list, geological history, and graphic / written logs detailing the rocks to be studied, will be forwarded in advance of the course to those enrolled.
Please note that for each course you will need to:
- Arrange your own transport
- Bring your own packed lunch, and any refreshments (e.g. flask of coffee, fruit juice, mineral water etc.)
- Wear strong footwear with good tread and ankle support, and have waterproof clothing with you in case weather is poor.
- Wear a hard hat (we will often be close to overhead quarry/cliff faces) – if you do not possess one of these, let me know in advance and I will provide you with one for the day.
You would be insured against accident for the duration of each course.

May 7th - Numerical modelling of sedimentary systems

Bath Geological Society - May lecture
Numbers, models and layered rocks: what can we learn from numerical modelling of sedimentary systems?
Professor Peter Burgess, Head of Department of Earth Sciences, Royal Holloway, University of London
While many other areas of science, for example physics and chemistry, can use experiments to help understand how physical systems work, sedimentary geology has for most of its history been limited to observation of natural systems recorded in outcrop and beneath the surface in sedimentary basins. This has been especially problematic for our understanding of how sediments from modern depositional systems, for example deltas and shallow carbonate seas, are incorporated into the stratigraphic record and preserved as layered rocks or strata. An understanding of how sediments are deposited and preserved as strata is key to our understanding of Earth surface systems, and also of significant economic interest for water and hydrocarbon resource exploitation. New developments in the numerical modelling of sedimentary systems have much potential to address many of these issues. This talk will focus on examples of numerical computer modelling and attempt to show how results from these models are changing how we think about the nature of strata. Perhaps most importantly, the examples demonstrate how new hypotheses can be generated from these models, to drive a new generation of data collection from sedimentary rocks in outcrop and in the subsurface.
