This layer of the map based index (GeoIndex) shows the location and name of active mineral workings in the UK and is derived from the BGS BritPits (British Pits) database. The BritPits database of onshore mineral workings in the UK is based on the records of the BGS, the Coal Authority, industry sources and the Valuation Office Agency (Minerals) and is maintained by the BGS Onshore Minerals and Energy Resources Programme. The database describes individual workings, both currently active and formerly worked, in terms of name, location (including Mineral Planning Authority), ownership, basic geology, commodity produced and end-uses. Contact details including the operator name, address, postcode and telephone and fax numbers are held where known. The location of over 6000 workings are held, with about 2000 currently being worked. The data can be produced digitally, under licence, in formats to meet customer requirements, such as locations of workings or operator addresses, and is suitable for use in GIS applications using the British National Grid. Although the GeoIndex is updated at regular intervals more information may be available than is shown at any one time.

This layer of the map based index (GeoIndex) shows the locations of known mines, mineral showings and localities, including sites where minerals of economic interest have been identified in panned concentrates. The information for the index is taken from the Mineral Occurrence Database. The Mineral Occurrence Database holds information on mineral occurrences in the UK including locations of known mines, deposits, prospects and mineral showings, including sites where minerals of potential economic interest have been identified in panned concentrates. Data is normally taken from published sources or from internal BGS records, such as field sheets, rock and stream sediment collection cards. Data compilation started ca. 1994 and the database currently holds about 13 000 records, but details of many more old workings and occurrences remain to be added.

ENVIX (Environnement de Vix) est le système d'information géographique et archéologique développé dans le cadre du PCR de Vix coordonné par C. Mordant et B. Chaume pour comprendre les dynamiques et les modalités d'occupation de l'espace pour la protohistoire et l'époque romaine. L'application contient les informations issues des relevés GPS en forêt (près de 13000 structures), d'inventaires archéologiques et des données environnementales.

La LINEM, etablie a Brest a ete creee en 1975 par le BRGM et le CNEXO. Elle gere plus de 7 000 echantillons qui sont, pour l'essentiel, constitues de section des carottes des sediments superficiels et de fragments de roches. Ils sont mis a disposition de la communaute scientifique et industrielle nationale et internationale.
