Geological Survey of Sweden

not to be confused with the Geologiska föreningen (Swedish: Geologiska föreningen)

Geological Survey of Sweden (Swedish: Sveriges geologiska undersökning, SGU) is a Swedish government agency that was founded by Axel Erdmann in 1858, that supervises all mineral deposits activities (surveys and extractions) in Sweden, and further the development of knowledge in the field of geology. The institution also has the right to issue instructions regarding groundwater administration in Sweden.

The purpose of the Geological Survey of Sweden is to undertake surveys and provide information on bedrock, soil and groundwater in Sweden. The SGU is in charge of providing local authorities with comprehensive geological information for environmental work and infrastructure planning. The SGU runs the Mineral Resources Information Office in Malå.

The SGU is responsible for maintaining the country's "High-Quality Groundwater" policy and set up the standards for "good" urban development, and to dispose properly of the country's unused civil defence readiness oil stocks facilities.

Two advisory bodies lead the SGU: the Advisory Council for Mineral Resources and the Advisory Council for Minerals Exploration. The SGU is the governing authority of the Mining Inspectorate, which issues permits for exploration and exploitation of mineral deposits in Sweden.

Each year, the SGU awards grants for targeted basic research and applied research in geosciences.

The Geological Survey of Sweden houses a rich collection of ore samples from all over the world. Visitors pay 1,000 Kronor (US$110) a day to examine the items on display. The national drill core archive in Malå features over 3000 kilometres of drill cores from across the nation.

The Geological Survey of Sweden was founded in 1858.
