Talks for 2023-24 season

22 January 2024 7:30pm
Prof James Rose, Royal Holloway University
“The earliest Humans in the British Isles - the geological context”
26 February 2024 7:30pm
Dr Thomas Jones, Lancaster University
"Pulling apart magma and the associated control on eruption style." The breaking apart of magma into fragments is intimately related to the eruptive style and thus the nature and footprint of volcanic hazards. Basaltic magmas, like those found in Hawaii and Iceland, do not fragment in a brittle manner, rather they break apart due to ductile processes. We currently lack models and fragmentation criteria to explain this ductile fragmentation and cannot predict the sizes and shapes of the resulting fragments. In this talk I will highlight some of the field, laboratory, and numerical work that we have conducted to unravel ductile fragmentation processes in basaltic systems.
25 March 2024 7:30pm
Ian Fairchild, Emeritus Professor, University of Birmingham
"Scotland's Greatest Ice Age"
22 April 2024 7:30pm
Chris Darmon, Down-to-Earth editor

Previous talks in 2023-24 season

25 September 2023
Dr Alan Richardson, BCGS
“Back to Basics - Can New Geological Discoveries Still Be Made With Hammer and Handlens?” This was a shorter talk than usual, followed by a discussion of future of TVGS. On display was the amazing Martley geology along with stunning minerals showcased by Margaret Rodway.

Pof Stuart Robinson University of Oxford
“Geological perspectives on climate change: from our local rocks to the IPCC” Abstract: “It has long been recognised by geologists that Earth's climate has changed over timescales of thousands to millions of years. Understanding the record and drivers of these past changes informs our knowledge of the environmental history and biotic evolution of our planet but also provides insights into ongoing, and future, anthropogenically-forced, climate change. Critically, the range of past climate states represented in the geological record allow us to probe the major controls and mechanisms that affect climate over a range of atmospheric CO2 levels. This allows us to offer perspectives on Earth system variables that are critical to predicting future climate change, such as climate sensitivity to CO2 (the amount of global warming that will occur in response to a doubling of atmospheric CO2). This talk will explore some of the ways that geologists reconstruct past climates and discuss examples of how the geological past can contribute to predictions of the future.”

Demonstration of the use of a drone to help log the geology of a local exposure. Carl went to a local site to fly his drone then went back to Martley Memorial Hall to see the results of some of his work and after that, there was a talk by Prof. Ian Fairchild on the Birmingham Erratics, along with a glass of wine and access to the library.
