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
Disseminations of the ore minerals in clastic sedimentary rocks characterize this deposit type. Deposits occur in marine, paralic, lacustrine, and continental host rocks at or near a redox boundary. Three subtypes are distinguished on the basis of the major, economically-viable commodity and on the relation to the redox boundary. Sandstone uranium (8.1) and sandstone lead (8.2) deposits are associated with reductants within porous oxidizing sandstones; sedimenthosted stratiform copper (8.3) deposits occur in reduced host rocks adjacent to redbeds.
