Till and soil sampling survey, NTS 42D, E, northwestern Ontario, 1999.
(requires an Internet connection)
Humus, B- and C-horizon samples of subglacial till were collected in 1999 over the Trans-Superior Tectonic Zone in the Killala Lake – Coldwell area of northwestern Ontario. 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.
Geochem Maps Available:
Diagrams summarizing the distribution of those sample sites anomalous in gold, kimberlite, base metal or rare element carbonatite signatures.
Pebble lithologies; heavy minerals for kimberlite indicator minerals and metamorphic or magmatic massive sulphide indicator minerals.
