Records of boreholes, shafts and wells from all forms of drilling and site investigation work. Some 850,000 records dating back over 200 years and ranging from one to several thousand metres deep. Currently some 50,000 new records are being added to the collection each year. These will be included in GeoIndex each time it is updated.
Many of the boreholes link to free online scans. See http://www.bgs.ac.uk/data/boreholescans/home.html for more information. Or use the GeoRecords Plus+ service: http://shop.bgs.ac.uk/georecords/
