Problems in the geochemistry of ore-bearing structures


, : Problems in the geochemistry of ore-bearing structures. Geologiya Rudnykh Mestorozhdeniy 9(5): 98-105

A combined geological-geophysical-geochemical method is proposed for the search for deep-seated ore deposits associated with concealed deep-seated fractures in the earth's crust. Geological and geophysical methods should be used to determine the location, history, and characteristics of development of the fractures, as well as the geometry of associated intrusions. The selection of areas for exploratory drilling should then be based on geochemical analysis of rare and ore-forming elements in unconsolidated deposits and bedrock designed to identify primary aureoles of endogenic ore bodies. The method is illustrated with particular reference to the rare metal deposits of eastern Transbaikalia (USSR).
