National Geochemical Reconnaissance NGR 1-76, Regional lake sediment geochemical reconnaissance data, Eastern Ontario (NTS 31C)
This file relates to data acquired under the Federal-Provincial Uranium Reconnaissance Program, the provincial part being financed through the Canada-Ontario Agreement on a Uranium Reconnaissance Program.
The project was jointly planned by the Geological Survey of Canada and the Geological Branch, Ontario Ministry of Natural Resources. The contracts for field work, sample preparation and sample analysis were let, supervised and monitored by the Geochemistry Section, Geological Survey of Canada.
The survey covers some 8600 sq. miles at an average sample density of 1 sample per 5 sq. miles. Samples were analyzed for 12 elements (Zn, Cu, Pb, Ni, Co, Ag, Mn, Fe, U, Mo, As and Hg) and loss-on-ignition to estimate organic carbon content.
The file consists of 26 geochemical maps, the area being divided into 2 sheets, 2 sample location maps and lists of the field and analytical data.
