The following pictures record a field visit by the Open University Geological Society (OUGS East Midlands Branch) to the Bantycock opencast gypsum mine, near Newark, Nottinghamshire, on 18 May 2008. Bantycock Mine – more correctly a quarry – is owned and operated by BPB British Gypsum Ltd, and is located on the outskirts of Balderton, SK 815 495. Our guides were Dr Noel Worley, Chief Geologist, and Jeff Torr, Mine Manager. This quarry provides the best section in the UK of the Triassic-Jurassic boundary. All photographs, including those of gypsum samples collected during the visit, were taken by David Bate.
