Talk by Emeritus Professor Ian Fairchild, University of Birmingham Abstract: The Port Askaig Formation were the first Precambrian rocks interpreted as glacial in origin, anywhere in the world. Now we know that Neoproterozoic glaciation was global in distribution. The exposures of the Port Askaig Formation are also the best permanent exposures of glacigenic deposits of […]

But there was one way in which it disappointed me. When I began collecting fossils and minerals and taking an interest in Geology, it seemed to have […]
Talk by Dr. Colin Summerhayes, Emeritus Associate, Scott Polar Research Institute, University of Cambridge Abstract: Given the magnitude and rapid rise of greenhouses gases(including water vapour), their long lifetime in the atmosphere, and the present disequilibrium in Earth’s energy budget (expressed as the Earth’s Energy Imbalance, or EEI), both temperatures and sea level must continue to […]
Talk Dr Sarah Sherlock, Senior Research Fellow, The Open University Abstract: My current preoccupation is to find new ways in which we can increase the spatial resolution of Ar/Ar laserprobe dating to extract new information from rocks and minerals. Through this I, and colleagues, are investigating the diffusion mechanisms of argon in feldspars, understanding the […]
