BRITISH GEOLOGICAL SURVEY The full range of survey publications is available from the BGS Sales Desk at Nottingham and Edinburgh; see contact details below or shop online at www.thebgs.co.uk The London Information Office maintains a reference collection of BGS publications including maps for consultation. The Survey publishes an annual catalogue of its maps and other publications; this catalogue is available from any of the BGS Sales Desks. The British Geological Survey carries out the geological survey of Great Britain and Northern Ireland (the latter as an agency service for the government of Northern Ireland), and of the surrounding continental shelf, as well as its basic research projects. It also undertakes programmes of British technical aid in geology in developing countries as arranged by the Department for International Development and other agencies. The British Geological Survey is a component body of the Natural Environment Research Council. ii Keyworth, Nottingham NG12 5GG ☎ 0115-936 3241 Fax: 0115-936 3488 e-mail: sales@bgs.ac.uk www.bgs.ac.uk Shop online at: www.thebgs.co.uk Murchison House, West Mains Road, Edinburgh EH9 3LA ☎ 0131-667 1000 Fax: 0131-668 2683 e-mail: scotsales@bgs.ac.uk London Information Office at the Natural History Museum (Earth Galleries), Exhibition Road, South Kensington, London SW7 2DE ☎ 020-7589 4090 Fax: 020-7584 8270 ☎ 020-7942 5344/45 e-mail: bgslondon@bgs.ac.uk Forde House, Park Five Business Centre, Harrier Way, Sowton, Exeter, Devon EX2 7HU ☎ 01392-445271 Fax: 01392-445371 Geological Survey of Northern Ireland, 20 College Gardens, Belfast BT9 6BS ☎ 028-9066 6595 Fax: 028-9066 2835 Maclean Building, Crowmarsh Gifford, Wallingford, Oxfordshire OX10 8BB ☎ 01491-838800 Fax: 01491-692345 Parent Body Natural Environment Research Council Polaris House, North Star Avenue, Swindon, Wiltshire SN2 1EU ☎ 01793-411500 Fax: 01793-411501 www.nerc.ac.uk
