Aberdeen Geological Society

Welcome to AGS

Welcome to and thank you for visiting our web-site. Aberdeen Geological Society comprises a lively mix of professional geologists (both working and retired) as well as amateurs from different career backgrounds, all with a shared enthusiasm for things geological. We aim to share knowledge, experience and keep interest alive by scheduling a programme of evening talks given by guest lecturers during the winter months and a series of guided field excursions from May through the summer months.

Forthcoming Events

Although our schedule of Field Excursion 2026 programme, finished with a long weekend to the Northern Cairngorms, covering 4 sites with particular glacial morphology, we have 2 further outdoor days in November when we hope to clean up a rock outcrop in the Donside Nature Reserve at the Brig o’Balgownie.

Also, we have now finalised our winter 2026/2027 programme of Thursday evening lectures which are scheduled from October ’26 through to April 27. The next 10 events are listed in the ribbon below.

									How can Aberdeen heat homes and buildings more sustainably while supporting a fair and practical energy transition for its communities?
The Aberdeen Geothermal Feasibility Pilot (AGFP) is exploring whether geothermal heat could become part of the answer by gathering the first direct subsurface evidence needed to assess the city’s potential. A research project funded by UKRI-NERC and led by the University of Aberdeen, AGFP combines an instrumented on-campus research borehole with a dense passive seismic survey across the city to map the subsurface to depths of up to 5 km. Together, these data will improve understanding of temperature, geology, groundwater, fractures, and rock properties beneath Aberdeen, helping to reduce uncertainty and inform future geothermal decisions. The project also addresses the wider barriers to geothermal uptake in cities like Aberdeen, including investment risk, public awareness, skills transition, heat network readiness, and fuel poverty. By linking subsurface science with education, community engagement, and practical planning, AGFP is helping to make geothermal more visible, credible, and achievable. It aims to combine open-access data and local partnerships to advance geothermal from a promising idea into a realistic option for Aberdeen’s just energy transition.







Dr David Cornwell is a Senior Lecturer in Geophysics at the University of Aberdeen and an observational geophysicist and seismologist specialising in imaging and monitoring the Earth’s subsurface. He holds degrees in Geophysics, Exploration Geophysics and Seismology from Leicester and Leeds, and his research spans ambient seismic noise, geothermal exploration, tectonics, earthquake hazards, and subsurface imaging. He is Co-Lead of the Aberdeen Geothermal Feasibility Pilot, which is using research drilling, city-scale seismic imaging and fibre-optic monitoring to investigate Aberdeen’s geothermal potential.

									Event Details

									This is a advance notice of a rather unique excursion, where we will be involved in cleaning up an outcrop of rock on the south bank of the River Don close to the old Bridge of Balgownie.  We have been in communication with Aberdeen City Rangers Service for some time, who are very keen to participate in this project.
The project is described in a document within our Special Features Table.
Aberdeen Ranger Service are leading the project and their team of volunteers will be responsible for clearing the access path and stairs. However, AGS need to supply the team to work on the rock outcrop itself.  Volunteers will work around the time of low water because the beach area alongside the rock does get wet at high water times.
We hope that we can get perhaps 5 or 6 members to help – perhaps by staggering attendance times between 9:30 and 14:30.
The clean up should take no more than the 5 hours but we have allocated a second day as contingency and so that we can take photos and measurements.
The Rangers have asked that we create material for an public information board to replace one on the public path near the top of the steps leading down to the beach area and rock itself.
We see that this is a great opportunity to promote AGS and bring geology to a wider audience within Aberdeen.

									This is a advance notice of a second day after cleaning an outcrop of rock on the south bank of the River Don close to the old Bridge of Balgownie.
The project is described in a document within our Special Features Table.
Please see details on day 1 – 2nd November event.
We hope that the cleaning work will be finished but we may need a few hours for contingency.  WE would however like to use this period to properly photograph the rock, make sketches and measurements.
This will be useful material for an public information board to replace one on the public path near the top of the steps leading down to the beach area and rock itself.
We see that this is a great opportunity to promote AGS and bring geology to a wider audience within Aberdeen.

									This is an evening talk by Mike Shepherd.
Thomas Francis Jamieson (1829-1913), born in Aberdeen, was an amateur geologist and the factor (estate manager) of the 11,000-acre Ellon Estate. A leading light of the 1860s glacial revival, he established several modern concepts in glacial geology, most notably the theory of glacial isostasy (that the weight of ice sheets depresses land masses).
When, in 1840, the Swiss geologist Louis Agassiz proposed Scotland had experienced the effects of the Ice Age, few British geologists took him seriously. But then, in 1862, Jamieson established from mapping glacial striae and the direction of travel of erratic boulders in the north of Scotland that thick ice sheets had spread out radially from the Scottish Highlands. A year earlier, Charles Darwin asked Jamieson to check the fieldwork forming the basis for Darwin’s 1838 paper on the parallel roads of Glen Roy. Darwin had suggested that the three terraces in the glen were beaches. Jamieson established evidence that they were the strandlines of an ice-dammed lake. Darwin agreed, writing to Jamieson that, ‘My paper is one long gigantic blunder,’ adding, ‘Did I not say that you would be able to settle the question?’

Biography: Born in Aberdeen when the Earth was young, Mike gained an honours degree in geology and mineralogy from the University of Aberdeen. Thereafter, he worked for oil companies in the North Sea, specializing in geological methods of locating the remaining oil in mature producing fields. This was the basis for his textbook, Oil Field Production Geology (AAPG 2009).He is retired and now writes local history books, such as how Bram Stoker came to write Dracula in Aberdeenshire. His research on Thomas Jamieson, near completion, will be used to write a book about this Ice-Age geologist.

									Jacobites and Jewellery: 4 centuries of artistry from Portsoy Marble
For over 350 years, from Jacobite times to the present day, the rock known as Portsoy Marble, has featured in international trade, high-quality masonry, tourist trinketry, and scientific research. It has been represented at national and international exhibitions and recorded in numerous tourist guides and textbooks. Most notably, it is reputed for incorporation in the Palace of Versailles by Louis XIV. The lecture brings together the evidence from trade with France, church monuments, local newspaper stories and advertisements, scientific presentations, and modern sculpture to show how the use of this local stone has evolved in a changing society.
Note that the title image of the “Turra Coo” is beautifully sculpted in Portsoy marble.

John Parnell is Professor of Geology and Petroleum Geology at the University of Aberdeen, where he arrived in 1999. He works on sedimentary geochemistry, including projects about Mars and the Moon, but lately he has also worked on topics involving local history. At Portsoy, he combines historical work with lunar analogue studies.

Website Content – What’s New

October ’26:

The winter lecture programme features 10 events. (Please check the ribbon above.) Please note that the dates and lecturers are fixed but some details are preliminary at this stage and will be updated closer to the event itself.

We are working with Aberdeen Ranger Service to clean up a rock outcrop and make it a special feature in the Donside Nature Reserve. 2 events have been added and 2 documents added to the Special Features table describing this unique special project.

Five new albums have been added to the Gallery – the photos are from the 30th August excursion to Skatie Shore, the 19th September to Cairn Gorm, 2 associated with Glen Roy & Glen Turret on the 20th September and the 5th concerns Glen Einich on 21st September.

With all the excitement around the Bayeaux Tapestry exhibition in London, we are very grateful to member, Craig Lindsay, who has discovered a missing panel of a similar tapestry. We are pleased to show this amazing panel – downloadable from our Special Features table.

All 20 volumes (1922 to 1988) of the Deeside Field are now available from our Archive, Also please check the section at the foot of the Features /Deeside Field page where we suggest articles that are appropriate to current AGS activities. 3 further articles have been added to this list of recommended articles.

Please note that Hugh Morel has stood down as Treasurer. We thank Hugh for sterling service over the past years and are pleased to welcome Justin Thomas as his replacement. (See Membership/AGS Officials for details)
