Survey Description


During the summer of 1977, helicopter-supported lake sediment and water sampling was carried out on the Melville Peninsula, Nunavut.  Samples were collected at an average density of 1 sample per 13 km2.  Sample site and grid cell duplicate samples were routinely collected in each analytical block of twenty samples.  The data were published in Geological Survey of Canada Open File 521 in 1978.

Data from this survey was included as part of a compilation map series and can be found in GSC Open File 738 published in 1981.

In 2009, the lake sediment samples were reanalysed by ICP-MS and INAA.  These new data are published in GSC Open File 6269, which also includes data previously released in OF 521 and OF 522 (NTS 46O, P, 47A).

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