Till, Indicator minerals
Till sampling survey, NTS 31 M/5, Lake Timiskaming area, northeastern Ontario, 1997.
(requires an Internet connection)
In 1997, several shallow trenches were excavated into the Peddie kimberlite, Lake Timiskaming area, northeastern Ontario. Glacial sediments (including till) were collected overlying, up-ice and down-ice of the Peddie kimberlite. 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.
