World Data Base. Part 2: the Precambrian Canadian Deposits (with emphasis on precious metal distribution) (CODES publication 9)

Abstract

The Precambrian of Canada contains numerous volcanogenic massive sulphide deposits which display a variety of host rock types, ore body mineralogy, zoning, morphology and metal content. This literature survey was aimed at documentation of the relationship of precious metals to base metals and their zonation within deposits. The publication "Precambrian Sulphide Deposits" edited by Hutchinson, Spence and Franklin (1982) has provided much of the information reported on here. Classic review papers by Sangster (1972), Hutchinson (1973) and Franklin et al. (1981) plus Vol. 70 of Economic Geology "An issue devoted to Canadian Mineral Deposits" provided both an overview and specific deposit data. This study does not go into detail on such topics as alteration patterns, host rock geochemistry, deformation, metamorphism or ore mineralogy. Information of this nature has been noted on data sheets which are available in the AMIRA project files.
