SUMMARY:Stratigraphy & Sedimentology of Northern European Chalks
DESCRIPTION:given by Dr Haydon Bailey\, HGS Chairman\, Past GA president & geological advisor to the Chiltern Society \nAbstract:\n \nThe Upper Cretaceous Chalks of Northern Europe appear\, on the face of it\, to represent sedimentation during an extended period of relative tectonic and environmental stability. Nothing could be further from the truth. These uniform\, white\, fine grained carbonates are the sediments resulting from constant change in water temperature\, oxygen content\, dynamic water currents both at the sea surface and at depth.  \nBack in 1994 I presented a talk at a European conference entitled “Chalk\, white\, as above!”\, because that was the comment frequently seen on core logs\, geologists’ description sheets and engineering geologists’ well logs. Just how much information were we losing because of this phrase? Over the last 30 years our understanding of chalk deposition\, and the environmental conditions which control it\, have fundamentally shifted. Hopefully I can convince you that this might be the case. \nView This Talk In The Members’ Section. \nThis replaced the scheduled talk on Critical Minerals from Geology to circular economy: A matter of national security planned to be given by Professor Kathryn Moore\, University of Exeter. This was due to bad weather. Kathryn’s talk will be rescheduled to a later date. \n

SUMMARY:Critical minerals from geology to circular economy: a matter of national security
DESCRIPTION:talk given by Associate Professor Kathryn Moore\, University of Exeter \nAbstract:\nWith the imminent release of a new Critical Minerals Strategy\, the UK is updating its approach to national security. In this lecture\, I will highlight the security issues that threaten critical mineral supply chains into the UK and into most countries. I will explain how mitigation of the risks requires ground – truthing\, based on an understanding of geology and material properties\, as well as wider socioenvironmental and political considerations. I will discuss how the needs of critical minerals production is a challenge in terms of skills requirement\, and why the discipline of geology has never been more important. \nUnfortunately this talk had to be cancelled due to communication issues caused by Storm Goretti. The talk will be rescheduled for a later date.
