Uranium provinces of North America — Their definition, distribution, and models Author: Finch, Warren Irvin Year: 1996 Category: Report <p>Uranium resources in North America are principally in unconformity-related, quartz-pebble conglomerate, sandstone, volcanic, and phosphorite types of uranium deposits. Most are concentrated in separate, well-defined metallogenic provinces. Proterozoic quartz-pebble conglomerate and unconformity-related deposits are, respectively, in the Blind River–Elliot Lake (BRELUP) and the Athabasca Basin (ABUP) Uranium Provinces in Canada. Sandstone uranium deposits are of two principal subtypes, tabular and roll-front. Tabular sandstone uranium deposits are mainly in upper Paleozoic and Mesozoic rocks Tags: usgs, gold placer deposits Nevada Source: ://pubs.usgs.gov/bul/b2141/plate-2.pdf
