 Dave Green's microscope course
WhenThu, 2 March, 19:30 – 21:30
WhereThe Chantry, Thornbury. (map)
DescriptionRocks and Minerals under the Microscope.  This 10 week course aims to introduce you to the identification and description of rocks and their component minerals under the petrological microscope. This is a practical course, each participant will be provided with a microscope and a set of thin sections of rocks, and will work through a course at their own pace. Held at The Chantry, Thornbury. First meeting 7.30 – 9.30, Thurs 12th January until March 23rd (not Thurs 16th Feb) in the Buckingham Room. Max. numbers 20, “first come, first served” due to number of slide sets. Cost £75

 Bath Geol Soc Lecture - Gas, geothermal energy and gold
WhenThu, 2 March, 19:30 – 21:00
WhereBath Royal Literary and Scientific Institution, 16 Queen Square, Bath (map)
DescriptionGas, geothermal energy and gold: the Earth’s crust as a percolator Professor Tom Blenkinsop, School of Earth and Ocean Science, Cardiff University Assessment of Earth’s finite natural resources becomes an increasingly urgent task as they are depleted, yet demand continues to rise. "Peak resources", the time at which production starts to decline, may occur within a few decades for some critical metals and oil. New methods of resource evaluation take advantage of the fractal geometry of georesources. Lode gold deposits, geothermal wells and volcanoes, and conventional and unconventional gas wells all have fractal characteristics that can be assessed by these techniques. These seemingly disparate resources are connected, as they form by fluid fluxes through the crust. Their origin can be considered as a consequence of percolation, bringing a further armory of theory to bear on understanding their formation and distribution.





Want to go to Annapurna?

Advert for Geology Trip to Annapurna

This has come my way and some of you may be interested. The illustration below is just a picture but the real PDF can be downloaded from HERE. The leader of the trip, Dr. Daniel D. Clark-Lowes, FGS, is based locally.


Corsham Walking Festival

Corsham Walking Festival

I have received the following which may find its way into your diary.

Corsham Walking Festival - 9 – 11 June 2017

Our lovely medieval town founded on weaving and stone quarrying, is at the very edge of the Cotswolds, and at the very heart of the Corsham Walking Festival.  From here a variety of walks will take you into the breath-taking rolling countryside of North Wiltshire, visiting local delights such as historic Lacock, Box and Castle Combe.  Corsham is now a ‘Walkers are Welcome’ town with many friendly places to eat, drink and shop.

Building on the success of the previous three Festivals this year we are offering 18 walks over 3 days, with an optional quiz, music and buffer supper on the Saturday evening.

Our wide ranging mostly themed walks feature such topics as geology, stone mines, Brunel’s railway and wildflowers.  Children’s treasure hunt and a newly devised Corsham Quest are also included to capture the imagination. 
Local history and lovely walks in the surrounding countryside there will surely be a walk just for you.  

Bookings for walks and the evening event will start on the 3 April.  
Please visit our website at for more information.


Somerset Geology Revived

The Somerset Geology Group

I recently received the following from Garry Dawson which, I am sure, will be of interest to many of you!

There is also an offer for unpaid internships to do the work - see at the end of this entry.


The Somerset Geology Group (SGG) is one of the natural history groups that operate in partnership with Somerset Wildlife Trust (SWT) and the Somerset Environment Records Centre (SERC). The Group was originally formed in 1984 to advise SWT and others on geological matters relating to planning and development. It has recently been re-formed and its role remains principally concerned with the conservation and promotion of Somerset’s geodiversity.

The newly reformed group has initially decided to focus on a review of Somerset’s Regionally Important Geological Sites (RIGS), which are now referred to as Local Geological Sites (LGS). In December 2016 we heard the good news that the Curry Fund of the Geologist’s Association have agreed to grant aid to support the sites review. This will enable us to start the review of Somerset’s LGS very soon with a view to completing the work within 2 years. 

Across Somerset 233 geological sites were identified as RIGS in the 1980s and 1990s. Following updated guidance from Defra on local sites (published in 2006) and several recent initiatives across the country encouraging awareness of geo-diversity at a landscape scale there is a need to review Somerset’s LGSs. The Curry Fund grant will allow us to ensure that we keep up the good work of earlier years by completing the LGS review. This will be done by geologists using LGS criteria & assessment forms (based on collated best practice from across the country) to carry out desk and site based assessments.

All members of SGG are volunteers. The Group normally meets twice each year; an e-Newsletter follows each meeting and is distributed widely. We are keen to involve as many geologists with an interest in Somerset as possible and to ensure that we have access to expertise across the geological sciences. There is no subscription or constitution. 
To become involved or find out more about SGG, please email Garry Dawson on     

Opportunities for Undergraduate and Post-Graduate Geological Internships

The Somerset Geology Group (SGG), in partnership with the Somerset Environmental Records Centre (SERC), is undertaking a project to review Somerset’s Local Geology Sites (LGS). These were formerly designated as Regionally Important Geology Sites (RIGS). 

To complete the site research and fieldwork for this review, SERC are seeking applications from geology undergraduates and post-graduates.  The interns will work on voluntary basis but training, travelling expenses and other support will be provided. We are looking for individuals able to commit a minimum of 3 months of their time to the project which is planned to run for two years. The main base of SERC is within the Somerset Wildlife Trust HQ in Taunton but interns may be required to work throughout Somerset. The project is supported by several organisations including the Curry Fund of the Geologists’ Association, Geckoella Ltd and Exmoor National Park Authority.

To apply send a 2-page CV, before 2nd June 2017, to Paula Hewitson at  Please indicate whether or not you hold a driving licence. For further details phone 01823 652446.   

More about Pen Park Hole

Pen Park Hole Video

You have about 3 weeks to see this BBC video about a descent into Pen Park Hole. The quality of the filming is excellent and the commentary is as good as we can expect. Click on the expand to full screen button to get the most from this.

As a retired gold mine geologist it confirms to me that large quantities of cash will be required to get me underground once more.
