Till Ontario 1999

Till sampling survey, NTS M/5, Lake Timiskaming area, northeastern Ontario, 1999.  


Geological Survey of Canada, Terrain Sciences Division

Survey Description

Till samples were collected at 30 sites in 1999 around the Peddie kimberlite, Lake Timiskaming area, northeastern Ontario. Four sites were sampled up-ice (north) of the kimberlite, and 26 sites were sampled down-ice (SW to SE). The data are published in Geological Survey of Canada Open File 4262. For comparison, the open file also includes data from 2 samples collected in a 1997 survey around the Peddie kimberlite and previously published in GSC OF 3775.

Data Description: Paper report or CD –ROM.

Quantities Analysed: <0.063, 0.063-0.25, 0.25-0.5, and 0.5 to 2.0 mm fractions by INAA; by LiBO2 fusion/ICP-ES for major elements; by LECO for C and S; by LiBO2 fusion/ICP-MS for minor and trace elements; by ICP-ES after aqua regia for base metals; by ICP-ES after a four-acid digestion for a duplicate suite of minor and trace elements.

Other Analyses: Heavy mineral concentrate for kimberlite indicator minerals.

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).
