Depth maps for the other Permo-Triassic basins (Eastern England and Wessex) are not considered as a viable geothermal resource because of the limited porosity and transmissivity of the reservoirs, and were not modelled.

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. Depth maps of relevant horizons taken from the Atlas of Onshore Sedimentary Basins (Whittaker et al., 1985) and revised where new data had become available since their production (e.g. detailed seismic interpretations) were used to provide and refine the main geological and structural models. The 1995 digital grids of the depth to top/base of the main aquifers were generated using the Interactive Surface Modeling (ISM) package, integrating both vertical and non-vertical faults identified in the seismic data. Grids were calculated at a 1000 m square node spacing and gridded at 200 x 250 m for the Cheshire Basin, providing the depth as a positive value below Ordnance Datum. The depth map for the Cheshire Basin presents minor differences in the west to the one published in Rollin et al. (1995). The maps for each basin were vectorised and merged into a single layer as part of the 2025 UK Geothermal Platform project.
