The Geoscience Data Repository (GDR), is a collection of Earth Sciences Sector geoscience databases that is managed and accessed by a series of Information Services (GDRIS). This site allows for you to discover, view and download, free of charge, the following information using these services:

• MIRAGE - Geoscience map images

  The GSC has published thousands of maps since the mid-1800's. More than 10,000 of these maps have been scanned and are available through the MIRAGE site.

• Digital geoscience maps

  The Geological Survey of Canada has published about 400 maps digitally. The geological polygons for approximately 250 of these maps are currently being made available to find, preview, and download as shape files through this map search tool.

• Aeromagnetic data

  Compilation grids (200m and 1000m) for Canada of residual total field and first vertical derivative; point and grid data for 300+ individual surveys.

• Gravity data

  Compilation grids (2000 m) for Canada of Bouguer, Free-air, horizontal gradient, first vertical derivative, isostatic, observed gravity; point data from the Canadian Gravity Database.

• Radioactivity data

  Compilation grids (1000 m) for Canada of Potassium (K), Uranium (eU), Thorium (eTh), Natural air absorbed dose rate, eU/K, eTh/K, eU/eTh from the NATGAM database

• Seismic and magnetotelluric data

  Seismic and magnetotelluric data from the 2002-2005 Lithoprobe project

• NGR geochemical data

  Geochemical point data (lake sediment, stream sediment, lake water, stream water) from the National Geochemical Reconnaissance database

• Geochemical survey metadata

  Searchable metadata for over 400 geochemical surveys conducted across Canada since the 1950s.

• Mineral deposits

  World Mineral Deposit Database and a Canadian Mineral Deposit Synthesis that describes important mineral deposit classes in Canada.

• Energy - Fossil Fuels data discovery tool

  Data related to fossil fuels (oil, gas, coal) in Canada; Canadian National Coal Inventory; analysis of borehole cuttings, core and outcrop samples, gasoline fraction, saturates, aromatics, hydrocarbon, geothermal observations.

• Canadian geochronology knowledge base

  The compilation represents publicly available reports of geochronological information for Canada

• Lexicon of Canadian Geological Names (CGKN)
