Marine bedrock dataset (DiGRock250k) version 3

Dataset description

DiGRock250k is a digital geological map showing the distribution of bedrock types in the UK Continental Shelf (UKCS) area, representing the natural continuation of the onshore bedrock geology into the offshore. The bedrock divisions on the map represent the principal lithostratigraphical units (e.g. formations and groups) in the UK, ranging in age from Proterozoic to Cainozoic in age, as defined in the BGS Lexicon of Named Rock Units. This dataset can be used in conjunction with other BGS offshore datasets that include: DiGSBS250k (Sea-Bed Sediments), DiGBath250k (Bathymetry) and the DiGHardSubstrate250k datasets. The bedrock geology below the sea-bed is of importance to a range of groups, including marine habitat mappers, marine spatial planners, the offshore construction and development sector, and the dredging and aggregate industries.


The usual BGS licensing terms and conditions apply to external use of the data. Data licence required.
