Till and soil sampling survey, NTS 42D, E, northwestern Ontario, 2000.
(requires an Internet connection)
Humus, B- and C-horizon samples of subglacial till were collected in 2000 in the Dickison Lake – Schreiber area of northwestern Ontario, west of the Trans-Superior Tectonic Zone. The Slate Islands located south of Terrace Bay and straddling the TSTZ were also sampled. The data are published in Ontario Geological Survey Open File Report 6056.
Paper report; digital data released in compressed ASCII, Excel and DOS files on diskette MRD-74 (Miscellaneous Release-Data 74).
B- and C- samples (no fraction stated) by ICP-AES for 15 elements; by INAA for 21 elements and by ICP-MS for 16 elements. Humus samples by ICP-AES-PGE for Au, Pt, Pd; by INAA for 20 elements and by ICP-MS for 24 elements.

Pebble lithologies; heavy minerals for kimberlite indicator minerals and metamorphic or magmatic massive sulphide indicator minerals.

The geographic extent of the survey is defined by the following polygons:
Covers NTS 42E/3 (Dickison Lake), 42D/14 (Schreiber), 42D/11 (Slate Islands) and 42D/10 (Pic Island) west of the Trans-Superior Tectonic Zone (TSTZ) in northwestern Ontario. It is bounded to the south by Lake Superior.
