Repurposing the Carboniferous
Because of 19th and 20th century coal mining and hydrocarbon exploration, a vast quantity of subsurface data has been accumulated on Britain’s onshore Carboniferous coal-bearing strata and the basins in which accommodated them. Despite this, many of the regional (structural and geodynamic) processes which governed Carboniferous basins remain poorly understood. Here, I will present some highlights from my recent PhD studies on the early Carboniferous evolution of basins in the northern Pennines. Understanding the nature of Britain’s Coal Measures has gained renewed importance given the need to reduce carbon emissions and seek alternative sources of energy.

Critical raw materials for the energy transition
Decarbonisation of energy and transport, to meet global net zero ambitions, will require significantly increased amounts of the raw materials used to manufacture batteries and other green technologies. Of significant importance are lithium, graphite, cobalt, and others which are used in battery manufacturing. Also of significance are the rare earth elements, particularly neodymium and dysprosium, used in motors of electric cars and wind turbines. It’s also important not to forget industrial commodities such as copper, which is essential for electrification. This talk will give an overview of those commodities most important to the transition, their current status and update on relevant BGS work.
Eimear is an economic geologist with research interests in critical metal mineralisation and geometallurgy, valorisation of mining waste, and mining heritage. She works on critical metal mineralisation research in Southwest England, with a focus on tungsten, bismuth and antimony in association with the Camborne School of Mines, and the EU Horizon 2020 HighTech AlkCarb Project to develop new geomodels for critical metal exploration in carbonatites and alkaline rocks.

Engineering geology: infrastructure delivery
Engineering Geologists are central to Scotland’s delivery of major infrastructure projects and achieving Net Zero. The fundamental importance of Engineering Geology to a range of infrastructure projects, including the A9 Dualling and the proposed Coire Glas pumped storage hydro scheme, will be explored in this talk. These same projects provide a valuable opportunity to encourage and upskill the next generation(s) of geoscientists and other STEM professionals as exemplified by Transport Scotland’s award-winning Academy9 initiative. The ongoing need for greater diversity in geoscience and engineering will be set out along with ways in which barriers to participation are being broken down.
Wednesday 1 December, 7 pm Dr Helen Fallas, British Geological Survey
Geoscience in the delivery of new planning policy for Scotland
Helen is a Chief Geologist with BGS and has research interests in groundwater systems and groundwater resources, particularly issues of demand, vulnerability and access and in sedimentology. Helen has been working as part of the Key Agencies Scotland sub-group tasked with understanding the environmental evidence and the evidence-based approaches required to inform the development, and delivery, of new planning policy approaches for Scotland’s future places and people.
Wednesday 15 December, 7 pm Fellows’ Night
This meeting, close to the anniversary of the foundation of the Society, is an informal meeting with a series of short talks given by members. Fellows’ Night will be held online this year using Zoom, with the same connection arrangements as the lectures. You will need to provide your own refreshments and party hat.
If you would like to contribute, please get in touch with Chris Lofthouse on firstname.lastname@example.org.

Life on land one-billion years ago: barren wilderness or evolutionary cradle?
The Torridonian deposits of the northwest Highlands provide a rare example of a billion-year-old sequence of terrestrial deposits, providing a critical insight into what life was like on land at this time. Fossils are represented by: (i) mat structures and trace fossils; (ii) dispersed microfossils recovered by palynological acid maceration; (iii) fossils preserved in phosphate nodules studied using thin sections. The latter represent a Lagerstätte as the fossils are exquisitely preserved in three-dimensions with labile cell contents remaining. The Torridonian fossil assemblages are surprisingly diverse, providing a snapshot of life on land at this time, and supporting the hypothesis that early life may have diversified on land rather than in the oceans.

Wednesday 2 February, 7 pm Dr Florian Fusseis, Edinburgh Univ.
How x-rays and neutrons allow us to challenge established concepts in tectonics
Florian is a Senior Lecturer in Structural Geology at the School of GeoSciences, University of Edinburgh. He leads process-oriented research in the related sciences of rock deformation, fluid-rock interaction and diagenetic/metamorphic processes, all with a growing interest in applied geosciences. An experienced field structural geologist, Florian is a leading developer of 4D in-situ x-ray imaging of processes in shear zones and other rock failures, e.g. in earthquake-prone regions.

The Forties (Rattray) Volcanic Province in the Central North Sea 1970 – 2020
Middle Jurassic volcanic rocks were discovered in the course of oil exploration in the North Sea in 1970, when the concept of plate tectonics was still in its infancy. A broad historical review reveals how subsequent interpretations of the volcanic province have benefitted not only from advances in the techniques of hydrocarbon exploration, but also from contemporaneous efforts to explain the origin and distribution of global volcanism away from plate margins. With the aid of examples from comparable mid-plate volcanic areas of various stratigraphic ages in Scotland and North Africa, a new synthesis of previous work is presented which raises doubts about recently proposed alternative models of North Sea volcanism and tectonics during the Jurassic.

Clogau Gold Mine exploration, North Wales
The Clogau-St David’s Gold Mine in Wales is the source of most of the UK’s gold, mined historically from very rich gold seams. Alba’s technical team are applying a multi-disciplinary approach, employing modern exploration tools such as 3D scanning & mine modelling, drilling from both the surface and underground, geochemistry, and geophysics. Mark has a career spanning four decades with a particular focus on gold.
Wednesday 2 March, 7 pm Clough Medal Lecture: Dr Tim Smithson, Zoology, Cambridge Univ.
A new beginning: recent discoveries in the early Carboniferous of northern Britain reveal rapid faunal replacement following the end-Devonian extinction
The end-Devonian extinction event marked a profound change in the diversity of vertebrates. The dominant Devonian taxa, the acanthodians, placoderms and sarcopterygians were suddenly replaced by minor components of the fauna, the actinopterygians, chondrichthyans and tetrapods. This replacement began in the early Carboniferous, coinciding with a fossil impoverished interval called Romer’s Gap, and evidence for it has been poor. Here we will consider how recent discoveries in the Ballagan Formation of northern Britain have shown that vertebrates recovered quickly following the end-Devonian extinction. Diversity was much greater than previously recognised and Romer’s Gap is an artefact of previous unsuccessful collecting.

The geology and evolution of near-surface fissure systems in Calabria, Itlay and other areas
Kit currently manages the Laser Ablation ICP-MS Lab at the University of Hull where he analyses a variety of materials on behalf of industry and academia. His personal focus is on developing techniques for radiometric dating of deformed geological fabrics.

The day a tsunami hit Scotland
Around 8150 years ago a huge submarine landslide caused a tsunami that hit many countries bordering the North Sea. Geological evidence shows that over 600 km of Scottish coastline were affected. This talk will look at what caused the tsunami, where it impacted and how sedimentological evidence has helped understand the number, direction and relative power of the tsunami waves. Modelling constrained by sedimentary evidence shows on the east coast of Scotland multiple waves over 6 m high penetrated >30 km inland flooding areas up to 11 m above sea level. Could this disaster happen again to Scotland?
