This dataset represents the modelled thickness in metres of the Sherwood Sandstone Group (SSG) in the main Permo-Triassic Cheshire, Wessex, Worcester and East Yorkshire-Lincolnshire basins, considered for their hot sedimentary aquifer geothermal resource potential. This dataset is derived from Rollin, K. E., G. A. Kirby, and W. J. Rowley. Atlas of geothermal resources in Europe: UK revision. British Geological Survey technical report WK/95/7, Regional Geophysics Group, 1995: https://webapps.bgs.ac.uk/data/publications/publication.html?id=21735106 and the European Geothermal Atlas (https://op.europa.eu/publication-detail/-/publication/9003d463-03ed-4b0e-87e8-61325a2d4456).
