The lithostratigraphy of the Blue Lias Formation (Late Rhaetian-Early Sinemurian) in the southern part of the English Midlands
Abstract
Mapping by the British Geological Survey in parts of Warwickshire and Worcestershire has shown the lateral continuity of three distinct lithological units at the base of the Lias Group. These have been named the Wilmcote Limestone, Saltford Shale and Rugby Limestone members of the Blue Lias Formation. The members can be recognized in the type section of the Blue Lias Formation at Saltford, near Bath and as far north as the Leicester area, the northern limit of that formation. Their correlatives can be recognized further north in Nottinghamshire and Lincolnshire, in the South Wales coastal sections and, with less certainty, on the Somerset coast.
