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
Mississippi Valley-type (MVT) lead-zinc deposits typically are composed of galena and sphalerite occurring as openspace fillings in carbonate breccias; replacement of host rocks is relatively minor except in high grade zones. The deposits owe their commonly accepted name to the fact that several classical districts occur within the drainage basin of the Mississippi River, central U.S.A. Important Canadian examples include Pine Point, Polaris, Nanisivik, Newfoundland Zinc, and Monarch-Kicking Horse deposits; of lesser importance are the deposits at Gays River, Nova Scotia and Robb Lake, British Columbia (Fig. 10-1).
