The Geological Survey of Canada is publishing a series of studies on indicator mineral geochemistry and other aspects of geochemical prospecting for diamond-bearing kimberlites.
Indicator minerals in glacial drift have proved important in finding kimberlites and in assessing their diamond potential. The GSC’s Bulletin 423, Diamond Exploration Techniques Emphasizing Indicator Mineral Geochemistry and Canadian Examples, by Charles Fipke, John Gurney and R.O. Moore describes indicator exploration methods for both kimberlites and lamproites, plus a general review of diamond geology.
Three open-file reports cover indicator mineralogy of glacial drift materials in the areas of Kirkland Lake, Ont., and Lac de Gras, N.W.T., and on the Central Plains. A fourth describes biogeochemical orientation surveys over kimberlites near Kirkland Lake.
The GSC Bookstore, 613 Booth St., Ottawa, Ont. K1A 0E8, can provide details on the open-file reports and the Bulletin. It can be reached at (613) 995-4342, by fax at (613) 943-0646, or on the Internet at
