Till Ontario 1997

Till sampling survey, NTS M/5, Lake Timiskaming area, northeastern Ontario, 1997.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

In 1997, glacial sediments (including till) were collected overlying, up-ice and down-ice of the Peddie kimberlite, Lake Timiskaming area, northeastern Ontario. Samples of weathered and fresh kimberlite were also collected. The data are published in Geological Survey of Canada Open File 3775. Two samples from this survey are included in Open File 4262 for comparison with the samples collected in 1999.

Data Description: Paper report and diskette of digital data (MS Excel, MS Word).

Quantities Analysed: <0.063, 0.063-0.25, 0.25-0.5, and 0.5 to 2.0 mm fractions by INAA for 35 elements; by XRF for 20elements. <0.063 mm fraction by ICP-ES after aqua regia for 23 elements.

Other Analyses: Heavy mineral concentrate for kimberlite indicator minerals and gold grains; pebble lithology.

Project History

1997-2002 Peddie kimberlite till surveys, Lake Timiskaming area, Ontario, carried out in 1997 and 1999.
  Samples of till and other glacial sediments as well as kimberlite were collected in 1997 and till samples were collected in 1999 around the Peddie kimberlite in the Lake Timiskaming area, northeastern Ontario. The purpose of the surveys was to document kimberlite mineralogy and glacial dispersal patterns as well as geochemical signatures associated with the kimberlites. The data are published in Geological Survey of Canada Open Files 3775 (1997 survey) and 4262 (1999 survey).
