Geology of Canadian Mineral Deposit Types
This volume defines and summarizes in a comprehensive and systematic manner the essential characteristics of all economically significant types of Canadian mineral deposits. These summaries reflect the current understanding of mineral deposits and correspond closely to the definition of mineral-deposit types in common use. A large color section serves to illustrate details of some of these mineral deposits, and locations of all known deposits are presented on an oversize figure and are indexed in an appendix, as well. Like previous volumes of this type, this volume will be a long-standing premier reference for academia, industry, and government institutions alike.
Abstract
Uranium vein deposits are concentrations of uranium minerals, such as pitchblende, coffinite, and brannerite, in fractures, shear zones, and stockworks . The uranium minerals are commonly accompanied by quartz and/or carbonate gangue. The mineralization is, as a rule, lithologically and structurally controlled. The vein deposits occur either (a) in shear or mylonite zones in various geological environments (veins in shear zones), or (b) within granitic or syenitic plutons or in rocks mantling granitic batholiths
