This review was commissioned by the BGS Stratigraphy Committee under the Chairmanship of John Powell and Colin Waters. It is based on a synthesis of new stratigraphical information on the Sherwood Sandstone Group acquired since the publication, in 1980, of the Geological Society of London Special Report ‘A correlation of Triassic rocks in the British Isles’ (Warrington, 1980). During this period, numerous BGS geological survey projects have acquired new knowledge of the Sherwood Sandstone Group succession in England and Wales, and many BGS colleagues provided us with information and expertise to assist with this review. Among these, we particularly wish to thank, D McC Bridge, N S Jones, J N Carney, A H Cooper, A J Newell, R G Crofts, A S Howard and S Holloway for information on local Triassic successions, advice on geophysical log correlation, and for comments on earlier drafts of the report.
The report has been edited by Joanna Thomas and has benefited from the comments of former and present members of the BGS Stratigraphy Committee, notably the chairman, John Powell, and his successor Colin Waters and from external reviews by Mark Hounslow and Nigel Mountney on behalf of the Stratigraphy Commission, Geological Society of London. Cartography in this report is by Paul Lappage and Henry Holbrook
