Abstract: A reconnaissance for radioactive minerals in the Shinarump conglomerate of Triassic age exposed north of the San Juan River at Balanced Rock anticline was made in July 1953. The purpose of the reconnaissance was to search for any exposed uranium minerals and to determine the favorability of the Shinarump for accumulation of uranium-ore deposits. No uranium minerals or places of abnormally high radioactivity were observed. However, nine exposed channels at the base of the Shinarump conglomerate and other channels, probably present where the base of the Shinarump is concealed, indicate the Shinarump may be favorable for uranium-ore deposits.

From abstract: A refraction seismic survey was made on Holiday Mesa, San Juan County, Utah, between May 21 and June 11, 1954, prior to an exploratory drilling program made by the U.S. Atomic Energy Commission to delineate channel trends in the area.

Abstract: Most of the uranium deposits in the Uravan and Gateway mining districts are in the persistent upper sandstone stratum of the Salt Wash member of the Morrison formation. Areas in which this stratum is predominantly lenticular have been differentiated from areas in which the stratum is predominantly nonlenticular. The most favorable ground for uranium deposits is in areas of lenticular sandstone where the stratum is underlain by continuous altered greenish-gray mudstone. Ore is localized in scour-and-fill sandstone beds within favorable areas of lenticular sandstone. Regional control of the movement of ore-bearing solutions in the principal ore-bearing sandstone zone is indicated by belts of discontinuously altered mudstone transitional in a northerly and southerly direction from an area of unaltered mudstone to areas of continuously altered mudstone ; and an area of unaltered mudstone in which no ore deposits are found and an increase in size, number, and grade of ore deposits from areas of discontinuously altered to continuously altered mudstone. Discrete regional patterns of ore deposits and altered mudstone are associated with Tertiary structures; where these structures and favorable host rocks occur in juxtaposition, regional controls appear to have localized ore deposits.

From abstract: The Happy Jack mine is in the White Canyon area, San Juan County, Utah. Production is from high-grade uranium deposits in the Shinarump conglomerate of Triassic age. The Shinarump strata range from 161/2 to 40 feet in thickness and the lower part of these beds fills an eastward-trending channel that is more than 750 feet wide and 10 feet deep.

From abstract: Uranium deposits and radioactivity anomalies have been found in the eastern half of the area underlain by the Browns Park formation in northwestern Colorado, south-central Wyoming, and northeastern Utah. The deposits are in eolian, lacustrine, and fluvial sandstones, tuffaceous sandstones, and limestones all of which were deposited on two converging pediments during Miocene time. At least one eastern and one western facies of lacustrine and fluvial sedimentary rocks are separated by a belt of eolian sandstones. The faces may be distinguished in the field and by petrographic and heavy-mineral studies in the laboratory.

The following document provides a mineralogical and geological map of the Colorado Plateau providing deposits and groups of deposits that have been found to produce 1,000 tons or more of uranium-vanadium within December 31, 1953.

A report about strata of conglomeratic sandstone which is localized st the base of the Brushy Basin shale member of the Morrison formation of Jurassic Age. These strata are discrete lithologic units which contain sedimentary structures oriented in a prevailing easterly direction.

From scope of report: "The fluorite district in the western part of the Thomas Range, Juab County, Utah, is one f the newest mining districts in western United States; since 1950 it has been the largest producer of fluorite west of the Mississippi River. The present report covers the geology of the entire fluorite producing area, and supplements an earlier report...on the individual mining properties."
