Geochemical data can be obtained from the following locations:

• Canadian geochemical surveys
  This is a catalogue of geochemical surveys conducted by the Geological Survey of Canada and its Provincial counterparts. The catalogue currently contains about 400 entries. This represents an estimated 70% of the GSC's data holdings and something less than 50% of the Provincial data holdings.

  For many GSC surveys, the raw geochemical data (released as GSC Open Files) are available for download, and can be located by searching the catalogue or browsing by category.

  The catalogue is also available as a Z39.50 service, which can be queried through these portals:

  • CGKN data catalogue
    (choose "GSC Canadian Geochemical Database" from the list)

  • Canadian Geochemical Surveys
    (Geoconnections Discovery Portal)

  Until the catalogue is complete, users should also search GEOSCAN (and any provincial equivalents) to locate additional surveys.

• National Geochemical Reconnaissance raw data
  Raw data for National Geochemical Reconnaissance lake and stream surveys can be downloaded from the Geoscience Data Repository. The user specifies a geographic bounding box which selects a block of data to download as a single package. The data may encompass several surveys, and analytical methodologies may vary slightly from one survey to another.
