Survey Description

Humus samples were collected in 1976 at a detailed scale in the Lac des Iles area, district of Thunder Bay in northwestern Ontario. The data are published in Ontario Geological Survey Map 80-800.

Data Description: Paper map with report in map margin.

Quantities Analysed: 0.30-0.80 mm, 0.16-0.30, <0.18 mm fractions analyzed by ICP-AES for 22 elements; by INAA for 9 elements, and by AAS for Ag; 0.16-0.30 mm and <0.18 mm fractions analyzed both by AAS after nitric acid-aqua regia and ICP-AES fluorescence spectroscopy after fire assay for Pt and Pd.

Project History

1986-1988 Northwestern Ontario detailed humus survey carried out in 1986.
  This small-scale survey is part of a series designed to examine the feasibility of using multi-element humus geochemistry for the location of gold, base metal or platinum group element (PGE) mineralization in areas of shallow overburden on the Canadian Shield of Ontario. The data are published in Ontario Geological Survey Map 80-800.
