G-BASE is a major BGS project that surveyed the surface geochemistry of the entire UK. Soil and stream-sediment geochemistry data is available for south-west England as a standalone dataset.
Generalised digital geological map data based on BGS's series of 1:250 000-scale maps, reclassified with lithostratigraphic nomenclature.
Buried valleys are ancient river or subglacial (beneath a glacier) drainage networks that are now abandoned and have become either partly or completely buried by more recent sediment.
