Seven uranium provinces that have yielded most of the uranium production in the United States, Canada, and Mexico are defined, described, and modeled in a new format. They are the Blind River-Elliot Lake, Athabasca Basin, Colorado Plateau, Rocky Mountain and Intermontane Basins, Gulf Coast, Basin, Gulf Coast, Basin and Range, and Florida Phosphorite uranium provinces.
Maps show the location of major uranium clusters within the provinces.
Most of the provinces appear to have formed in close associates with volcanic activity related to the development of the western margin of the North American Plate from Precambrian through Tertiary time. A strategy for monitoring glaciers, by A. G. Fountain, R. M. Krimmel and D. C. Trabant. This report outlines a strategy for monitoring glaciers in the United States. The strategy consists of three levels of surveillance. These surveillance levels would provide basic measurements, analysis, and reporting standards for the study of glaciers.
