The Rawlins Quadrangle (2/sup 0/), Wyoming and Colorado, was evaluated to identify areas that contain environments favorable for the occurrence of uranium deposits. Data from reconnaissance and detailed surface studies, aerial radiometric surveys, hydrogeochemical and stream-sediment reconnaissance surveys, and subsurface drill-hole log studies were collected and compared to favorability criteria developed for the National Uranium Resource Evaluation program. The authors delineated 15 areas containing 10 favorable environments as the result of the evaluation. Sandstone uranium environments occur in 11 areas. Two areas contain favorable carbonate uranium environments, and one is favorable for uraniferous lignites. Favorable plutonic environments occur in two areas, and favorable quartz-pebble conglomerates occur in two areas. Unevaluated environments include the Baggot Rocks Granite, the Frontier Formation, the Hanna Formation east of Elk Mountain, and the Medicine Bow and Mesaverde Formations in the Laramie Basin. All remaining areas in the quadrangle are considered unfavorable.
