Allan Lake Carbonatite Complex multi-media sampling, Algonquin Park, Ontario, 1984
The Allan Lake carbonatite was discovered as a result of a reconnaissance air-borne gamma-ray survey flown in 1977 under the Uranium Reconnaissance Program. Follow-up investigations in the fall of 1983 lead to the discovery of a glacial dispersal train composed of thorium-rich till and containing Th-bearing carbonatite boulders. Based on the results from a series of closely spaced flight lines and initial follow-up studies, ground investigations were initiated during the summer of 1984. These included in-situ gamma-ray spectrometry, till geochemistry, biogeochemistry as well as lake water and sediment geochemistry. Additional air-borne geophysical surveys were carried out in conjunction with the ground investigations. This study is published in Journal of Geochemical Exploration v.30.
