Geological Survey of Canada Open File 6476


The British Columbia Geological Survey, Geoscience BC and Natural Resources Canada - Geological Survey of Canada have collaborated to update the BC Geology Map (the Province's digital geology map) in central BC. The update area corresponds to Geoscience BC’s QUEST Project geophysical survey footprint, which extends from Williams Lake to Mackenzie (an area larger than Vancouver Island).


The revised geology for this region has been generated by geological, geophysical and geochemical experts from the three organizations. The project incorporates geophysical and geochemical data from Geoscience BC’s QUEST Project, geophysical data from Natural Resources Canada and recent bedrock mapping by the British Columbia Geological Survey. The BC Geology Map QUEST Area update focuses on the volcanic and intrusive rocks of the Quesnel Terrane in central British Columbia, which are prospective for copper and gold deposits but covered by glacial deposits in the center of the update area.  New interpretations are expected to benefit to the mineral exploration community working in the region. 

In addition to the new map for the area, the update is also being seamlessly incorporated into the digital bedrock geology for BC.  A preliminary version of the digital file is also available in shape or Manifold files as part of this release.  A second update will be released and incorporated into MapPlace when the final digital data is available.

Additionally, a draft copy of the digital BCGeologyMap, updated to include new information from the Bedrock Geology of the QUEST area map, is available for download. This draft of the digital BCGeologyMap is the starting point to streamline integration of past and future geological mapping results into the provincial database.  A future release will include enhanced metadata, cleanup of line work due to projections issues and the integration process methodology.



About BC Geology Map


The BC Geology Map is British Columbia’s online digital geology map, maintained by the British Columbia Geological Survey.  The map was originally compiled from geological maps by British Columbia Geological Survey, Geological Survey of Canada, university and industry geologists.  The digital geology is available for free through MapPlace ( or 2005 versions are available as GeoFiles 2005-1 to 2005-10.


All publications of the BC Geological Survey are available digitally, free of charge, from this website.
