Regional geological summaries

Geological regions

BGS have produced 13 summaries of the on-shore regional geology for England, Wales and Northern Ireland. The extents of the regional summaries areas follow the British Regional Geology (Regional Guides) series. They are intended to inform the general public of the geology in each of the regions covered. They have been written in the same format, in an easy to understand manner, and are intended to provide overviews of the geology of each of the regions covered. The summaries are stand-alone and contain a generalised geological map, cross sections ('vertical slices') through the geology and illustrations. Because of the variations in the geology and geological history in different regions the colour scheme used and the way the rock units are subdivided in individual accounts may vary.

The regional geological summaries for England, Wales and Northern Ireland form part of BGS's wider work on better communicating the geology of the UK. Their development has been financially supported by Radioactive Waste Management (RWM) and forms part of a wider BGS National Programme, funded by a range of stakeholders, to make our science publicly available and accessible to all. The regional geological summaries for Scotland are under development.


***These Regional Geological Summaries reports are NOT the published outputs of the BGS National Geological Screening exercise. The National Geological Screening reports are written for a technical audience to inform RWM in its discussions with communities interested in finding out about the potential for their area to host a GDF.***
