Soil, Till Ontario 1993

Soil and till sampling survey, NTS 42A, 32D, northeastern Ontario, 1993.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till samples were collected from 31 boreholes up and down-ice and over the C14, B30, A4 and Diamond Lake kimberlite pipes in the Kirkland Lake area, northeastern Ontario. Till samples were also collected over and down-ice from the Buffonta kimberlite dyke. Soil (humus, B- and C–horizon) was collected over and down-ice from the C14 and Diamond Lake pipes and the Buffonta dyke. The data are published in Geological Survey of Canada Open File 3228.

Data Description: Paper report.

Quantities Analysed: <0.063 mm fraction by ICP-ES for 33 elements, by fire assay-ICP-AFS for Au, and by XRF for Nb, Sr, and Zr. <1.0 mm non-magnetic heavy mineral fraction by INAA for 34 elements.

Other Analyses: Heavy mineral concentrate for kimberlite indicator minerals and gold and sulphide grains; matrix carbonate content; grain size.

Project History

1992-1996 Kirkland Lake, Ontario kimberlite project, 1992-1996.
  Till and soil samples from overburden drill holes up and down-ice and over kimberlite pipes were collected in 1993 as part of a 4-year project to refine or develop new techniques for kimberlite exploration and to evaluate the potential for the discovery of additional kimberlites near Kirkland Lake, Ontario. The study will also address the problem of lack of published information on glacial dispersal of kimberlitic debris. The data are published in Geological Survey of Canada Open File 3228.
