Survey Description

In July 2012, till samples were collected in central Nunavut along a 500-km long, roughly east-west transect across three major geologic domains: the Thelon tectonic zone, the Queen Maud block, and the adjacent Rae craton.  In total, 79 regional glacial sediment samples (mainly till; n=69) were collected in the study area. At most sites, one small sample (~3 kg) and one large sample (mean=12 kg; range=7.3-16.0 kg) were collected, mainly from active frost boils.

The data are published in Geological Survey of Canada Open File 7418.

The geographic extent of the survey is defined by the following polygons:

  • Covers parts of NTS 66E (Jervoise River), F (Pelly Lake), G (Deep Rose Lake), I (Ian Calder Lake), J (Joe Lake), K (Armark Lake), L (Macalpine Lake) and 76I (Overby Lake), the area south of Chantrey Inlet, central Nunavut.  The Thelon Game Sanctuary is located south of the study area, and the Queen Maud Gulf Migratory Bird Sanctuary to the north.

  • Covers part of NTS 56E/2 (untitled), /11 (untitled) and /12 (Nanau Lake) in central Nunavut.  It is located approximately 165 km south of Chantrey Inlet and 103 km north of Baker Lake.
