Survey Description

During the field seasons of 1987 and 1988, a total of 70 intact overburden cores were drilled with a Rotasonic drill in an area between Timmins north to Smoky Falls, northeastern Ontario.  Core samples were grouped into 3 categories: diamicton; well sorted, fine-grained sediments (predominantly lacustrine); and, sorted sand and gravel.

The diamictons were processed to provide clay, silt+clay, heavy mineral and pebble fractions for geochemical and lithological analyses.  Fine-grained sediments were processed to provide clay and silt+clay fractions for geochemical analysis.

The data are published in Geological Survey of Canada Open File 2278.
