Generalised digital geological map data based on BGS’s published poster maps of the UK (north and south). Bedrock-related themes were created by generalisation of 1:50 000 data to make the 2007 fifth edition bedrock geology map. Superficial gelogy-related themes were digitised from the 1977 first edition Quaternary map (north and south).
Many BGS geology maps are now available digitally. The Digital Geological Map of Great Britain project (formerly known as DiGMapGB) has prepared 1:625 000, 1:250 000, 1:50 000 and 1:10 000-scale datasets for England, Wales and Scotland. Work continues to upgrade these.
The geological areas (or polygons) are labelled or attributed with a name based on their lithostratographical, chronostratographical or lithodemic nomenclature and their composition (rock type or lithology). This information is arranged in two themes: bedrock geology and superficial deposits. Faults and other linear features are available in a separate theme.
Geology maps are the foundation for many other types of earth science-related maps and are of potential use to a wide range of customers. This dataset uses the themes:
- bedrock geology
- superficial (with mass movement)
- linear (faults) features
