Till Nunavut 1975

Till sampling, NTS 55M, 65P, Baker Lake area, Nunavut, 1975-1976.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

More than 2000 samples were collected in 1975 and 1976 in the Baker Lake area, Nunavut. The data were published in GSC Open File 1335. The samples were reanalyzed using improved analytical methods and republished in GSC Open File 3243. A Quaternary framework for drift prospecting in the area was published in GSC Bulletin 485.

Data Description: Paper report and paper maps (OF 1335); Paper report and 4 diskettes (ASCII, dBase3.0 and Excel 3.0) (OF 3243).

Quantities Analysed: <0.063 mm fraction by ICP-AES after hot nitric-aqua regia digestion for 31 elements; by INAA for 34 elements (OF 3243).

Geochem Plots Available: Proportional dot maps showing regional distribution of U, Au, Ag, As, Hg, Cu, Pb, Zn, Ni, Cr, Ba, Fe Mg, V, and Sr (OF 3243).

Project History

1970-1976 Keewatin drift sampling project, 1970-1976
  During the early seventies, the Geological Survey of Canada undertook a major study of surficial deposits in the District of Keewatin (now Nunavut) to examine the geochemical properties of till within perennially frozen, glaciated terrain and to establish a Quaternary geological basis for mineral exploration by drift prospecting. Initially the project focused on the Kaminak Lake area (1970-1975), but was later expanded to include much of the eastern District of Keewatin from latitude 60o (Manitoba border) to north of Baker Lake (1975-1976) (latitude 66o). The Kaminak Lake data are published in GSC Open File 146. The Baker Lake data are published in GSC Open File 1335 and GSC Bulletin 485.

1995-1996 Baker Lake, Nunavut reanalysis project, 1995
  Till samples originally collected in the Baker Lake area in 1975 and 1976 were reanalyzed to take advantage of improvements in analytical methods and to further define and expand on the geochemical properties of till in the Baker Lake area. The silt and clay-sized fraction of archived samples from the original project were analysed by both Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) and Instrumental Neutron Activation Analysis (INAA). The data are published in GSC Open File 3243.
