No environments favorable for uranium deposits occur within 1500 m (5000 ft) of the surface in the La Junta Quadrangle, Colorado and Kansas. The Triassic Dockum Group, the Jurassic Morrison Formation, and the Cretaceous Lytle Sandstone Member were studied in detail; if they exhibited favorable characteristics, they might be hosts for sandstone-type uranium deposits. However, hydrogeochemical and airborne radiometric data, the geologic literature, field examination, gamma-ray logs, and the four known occurrences do not indicate favorability. Other units in the surface and subsurface are also unfavorable. The Precambrian rocks, Pennsylvanian Morrow Formation, the Pennsylvanian and Permian Sangre de Cristo Formation, and the Cretaceous Dakota Sandstone are unevaluated.
