Janet Watson Lecture Theatre, The Geological Society, Burlington House, Piccadilly
London, W1V 0JU United Kingdom
+ Google Map

Henry Stopes Memorial Lecture by Professor Nick Ashton from the British Museum. The human settlement of Britain now stretches back to almost a million years, but it has been a history of brief incursions governed by the cyclical changes in climate and the changing status of Britain as an island or as a peninsula of the European Mainland. This talk will discuss research from the last twenty years that has provided new sites, better dating frameworks, rich environmental information and a…

The Halstead Lecture: The Secret Lives of Salt Giants

March 8 @ 6:30 pm - 8:00 pm
Janet Watson Lecture Theatre, The Geological Society, Burlington House, Piccadilly
London, W1V 0JU United Kingdom
+ Google Map

Talk by Sian Evans. From deposition to diapirism, salt has a unique impact on the stratigraphic evolution of a basin. Thick evaporite units deposited during ocean desiccation deform as a viscous fluid over millions of years, often resulting in profound structural complexity. Nature is more complex than we can imagine and the classic models of salt tectonics are unable to explain the diversity of structural styles and orientations that we observe. By using high-quality 3D seismic datasets from around the…
