BGS Geology 250k version 4
Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the dataset is 1:250 000, providing a generalised geology. Onshore coverage is provided for all of England, Wales, Scotland and the Isle of Man. Data are supplied as two themes: bedrock and linear features (faults). Superficial, mass movement and artificial themes are not available onshore at this scale. Bedrock geology describes the main mass of solid rocks forming the Earth's crust. Bedrock is p
