Setting and Origin of Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri Simplified geologic map of the Great Bear magmatic zone and locations of main deposits, prospects, and showings, and prospective iron oxide and alkali-altered systems.
Tectonic Origin of The Colorado Mineral Belt. by Rob Rice ES767 Spring 2015 What is the Colorado Mineral Belt? The Colorado Mineral Belt (CMB) is a ribbon of metalliferous hydrothermal deposits, resulting from Laramide-aged magmatic activity at the forefront of the Rocky Mountain orogenic event (Tweto and Sims, 1963).
Mineral deposit: Mineral deposit, aggregate of a mineral in an unusually high concentration. About half of the known chemical elements possess some metallic properties. The term metal, however, is reserved for those chemical elements that possess two or more of the characteristic physical properties of metals
Geologists examine all factors controlling the origin and emplacement of mineral deposits, including those containing gold. Igneous and metamorphic rocks are studied in the field and in the laboratory to gain an understanding of how they came to their present location, how they crystallized to solid rock, and how mineral-bearing solutions ...
