Survey Description


During the summer of 1978, lake sediment and water samples were collected on central Baffin Island, Nunavut in a Helicopter-supported survey.  The 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 GSC Open File 567 in 1979.  The samples were reanalysed by INAA for gold and 25 additional elements and published in 1999 along with the original data in GSC Open File 3716.

In 2018, the samples were reanalyzed by ICP-MS and the data are published in Canada-Nunavut Geoscience Office Data Series GDS2018-001.

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