Open File 2009-10

Open File 2009-10 presents a 1:50 000-scale bedrock geology map of the Quesnel River area (NTS 93B/16), encompassing and extending southeast of Quesnel, British Columbia and adjoining Open File 2008-06. It presents the results of new mapping, geochronological dating  and compilation of private industry research that provides new insight into the geologic and metallogenic evolution of this largely overburden covered portion of the Quesnel  terrane.

The analytical portion of this assessment was supported by the Geological Survey of Canada (Natural Resources Canada) through the Mountain Pine Beetle Program.
