Survey Description


In 1975, lake sediments were collected in North West Territories, southeast of Great Slave Lake.  The data are published in Geological Survey of Canada Open File 324.  Data for 131 sites were not published.

In 2012, samples collected at 2000 sites in 1975 from map sheets 75C (OF 324) and 75F (OF 325) were reanalyzed by ICP-ES/MS and are published in GSC Open File 7232, along with original data from OFs 324 and 325.

This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
