Digitized edition from print [produced by Natural Resources Canada]. "June 4, 1958." Cover title. Includes bibliographic references. "A new geochemical approach has been developed for relating the chemical composition of North American manganese deposits to the igneous rock from which they originated. The approach consists of specifying the nature and composition of amenable source rocks; of devising a leaching cycle during which certain constituents of the rock are solubilized; of specifying the conditions under which the solubility products of carbonate, oxide and related compounds are exceeded; of specifying the order and association in which the compounds would be precipitated; and of specifying the changes to be expected in aging of the deposit. The theoretical predictions agree well with observations on known deposits"--Abstracts, p. iii. gccst Chemistry Canada. Department of Mines and Technical Surveys. Canada. Mines Branch.
