Soil, Till Nunavut 1999

Till and soil sampling survey, NTS 55E,L, Kaminak Lake area, Nunavut, 1999.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till and humus samples were collected Kaminak Lake area, Kivalliq region, Nunavut in 1999. The samples were collected near Hg-rich sources identified in the 1997 survey. The data are published in GSC Open File 4089.

Data Description: Paper report; CD-ROM (PDF and Excel).

Quantities Analysed: <0.063 mm, <0.002 mm and <2 mm fractions by ICP-AES, by CV-AAS and Milestone for Hg, and by various methods for metal speciation-selective extraction analysis on selected samples.

Other Analyses: Pebble lithologies (2-4 cm fraction); carbonate (<0.063 mm, <0.002 mm and <2 mm (Chittick and LECO)); LOI; <0.002 mm by X-ray diffraction for clay mineralogy; heavy mineral concentrate for point counts.

Project History

1997-2002 Kaminak Lake, Nunavut till sampling surveys carried out in 1997 and 1999.
  In 1997 the Geological Survey of Canada initiated the five year Metals in the Environment Program (MITE) to address scientific issues related to natural and anthropogenic signatures of metals in the surface environment. Till surveys were carried out in the Kaminak Lake area, Nunavut in 1997 and 1999 to study the cycling of mercury (Hg) in soils underlain by permafrost. The work was part of a larger project designed to examine weathering processes and trace metal flux in the surficial environment at sites located in different ecozones and geological terrains across Canada. The data are published in GSC Open File 4089.
