This dataset is now superseded by Marine bedrock dataset (DiGRock250k) version 3. The BedRock data shows polygonal and selected linear geological information, sourced from published BGS 1:250 000 scale maps. Geological units are identified using BGS LEX-ROCK nomenclature that may differ from that on the printed maps. UK waters coverage is available with additional information from surrounding nations. The data is available in vector format. BGS licensing terms and conditions apply to external use of the data.
