Further geological information held by the British Geological Survey relevant to the London district is listed below. It includes published maps, memoirs and reports. Enquiries concerning geological data for the district should be a addressed to the Manager, National Geological Records Centre, BGS, Keyworth. Geological advice for this area should be sought from the Regional Geologist, Southern and Eastern England, BGS, Keyworth.
Other information sources include borehole records, fossils, rock samples, thin sections, hydrogeological data and photographs. A Geoscience Index System is available for consultation in BGS libraries and on the BGS web site (www.bgs.ac.uk). This is a developing system which searches indexes to the collections. It has a backdrop based on the 1:250 000 scale maps. Available indexes include:
- Index of boreholes
- Outlines of BGS maps at 1:50 000 and 1:10 000 scale and 1:10 560 scale County Series
- Chronostratigraphical boundaries and areas from British Geological Survey 1:125 000 maps
- Geochemical sample locations on land
- Aeromagnetic and gravity recording stations
- Land survey records

The 96 maps covering the four 1:50 000 series sheets of London (256, 257, 270 and 271) were resurveyed between 1970 and 1996 by A J M Barron, F G Berry, S J Booth, C R Bristow, R A Ellison, D H Jeffery, R D Lake, M McKeown, D Millward, R T Mogdridge, B S P Moorlock, A N Morigi, A Smith, P J Strange and I T Williamson.
Digital geological map data
In addition to the printed publications noted above, many BGS maps are available in digital form, which allows the geological information to be used in GIS applications. These data must be licensed for use. Details are available from the Intellectual Property Rights Manager at BGS Keyworth. The main datasets are:
DiGMapGB-625 (1:625 000 scale)
DiGMapGB-250 (1:250 000 scale)
DiGMapGB-50 (1:50 000 scale)
DiGMapGB-10 (1:10 000 scale)
The current availability of these can be checked on the BGS web site at:
