Northwest Alberta and northeast British Columbia kimberlite exploration project, 2003-2006
The Geological Survey of Canada and the Alberta Geological Survey initiated a four year collaborative project in northwest Alberta to create surficial geology maps and provide geoscience information in support of exploration for 1) shallow gas reservoirs in unconsolidated Tertiary/Quaternary sediments; 2) granular aggregate resources; and 3) kimberlitic bedrock. The project also extends into northeast British Columbia where additional studies have been conducted in collaboration with the British Columbia Ministry of Energy, Mines and Petroleum Resources to evaluate the mineral potential of the region northeast of Fort Nelson.
To evaluate the potential for kimberlitic bedrock in the Alberta study area, glacial sediment samples were collected in 2003, 2004 and 2005. The data (geochemistry, KIM, gold grains, Pb and S isotopes) are published in the following Open Files:
|GSC OF 5121/AGS Special Report 77||till geochemistry; KIM and gold grain data for selected samples|
|GSC OF 5545/AGS Special Report 87||EMP analyses of KIMs and sphalerite grains|
|GSC OF 5692/AGS Special Report 96||sphalerite and KIMs in 19 bulk till samples|
|GSC OF 7541||Pb and S isotopes of sphalerite and galena grains|
To help explain potential sources of KIMs found in northeastern British Columbia, additional sampling of glacial sediments (till and glacial fluvial) and stream sediments and waters in the Etsho Plateau region was undertaken in 2005. Based on the 2005 results, stream sediments and waters were also collected in 2006. The stream sediment and water data, including IM results are published in Geological Survey of Canada Open File 6311. Selected glacial sediment data are published in British Columbia Geological Fieldwork 2006.
