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.
After sampling for the regional survey was completed, an additional 131 sites were sampled in the centre of the mapsheet. These samples were analysed, but the data were not published in OF 324.
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.
In 2016, the data from OF 7232 (NTS 75C, F) were republished in OF 8010 with reanalyses of samples collected in 1975 in 75K (OF 326). OF 8010 also includes the original data from OFs 324, 325 and 326.
This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
