This dataset has been superseded, the latest version is BGS BritPits version 4 http://data.bgs.ac.uk/id/dataHolding/13608569 The BGS BritPits v3 is derived from a BGS database, which contains records of mineral workings covering the Great Britain, Northern Ireland, Isle of Man and Channel Islands. The coverage includes active, inactive, dormant and ceased sites and a range of mineral operations, including mines, quarries, onshore oil and gas fields, together with wharfs and rail depots handling mineral products and industrial processes which produce a mineral product. The information on currently active sites is continually updated with the cooperation of both local authorities and the minerals industry.
