Survey Description


Lake sediments were collected in 1975 in Northwest Territories and Nunavut, east of Great Bear Lake.  The data are published in GSC Open File 327.

After sampling for the regional survey was completed, an additional 262 sites were sampled in the centre of the mapsheet.  These samples were analysed, but the data were not published in OF 327.

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