| dc.description.abstract | Uranium resources of the Amarillo Quadrangle, Texas, were evaluated, using criteria established for the National Uranium Evaluation (NURE) program, to a depth of 1500 m (5,000 ft) using available surface and subsurface information. No surface uranium occurrences were reported in the literature. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, and geochemical anomalies, interpreted from hydrogeochemical and stream-sediment reconnaissance, were investigated. No uranium occurrences were located during a detailed rock sampling program. Areas of uranium favorability in the subsurface were evaluated using driller's log descriptions and gamma-ray well logs. On the basis of subsurface data, five areas of uranium favorability were delineated within the quadrangle. Two areas in the Triassic Dockum Group are in sand-rich facies. Two areas are in thick arkosic alluvial fan and fluvial facies of Early Permian and Pennsylvanian age. Early Permian arkosic strata cover the greatest area. One favorable area along and northeast of the Amarillo Uplift is characterized by abundant gamma-ray log anomalies that are concentrated in Wolfcampian (Early Permian) and older strata. Geologic units considered unfavorable are all Pleistocene strata, all the Tertiary Ogallala Formation, most of the Triassic Dockum Group, all post-Wolfcampian Permian strata, and parts of Lower Permian (Wolfcampian) and Pennsylvanian rock units. Recommendations for improving the reliability of this evaluation include drilling test holes for detailed subsurface information. | |
