From purpose and scope: The objectives of this cooperative investigation between the U.S. Geological Survey and Southwest Kansas Groundwater Management District No. 3 were (1) to update and interpret geologic and hydrologic information affecting the Ogallala aquifer in Ford County, and (2) to evaluate hydrologic conditions in the Ogallala aquifer in Ford County during 1980 and 1981.

Abstract: Uranium resources of the Lamar Quadrangle, Colorado and Kansas, were evaluated using National Uranium Resource Evaluation criteria. The environment favorable for uranium is the Lower Cretaceous Dakota Sandstone in the area east of John Martin Reservoir for south Texas roll-type sandstone deposits. Carbonaceous trash and sulfides are abundant in the Dakota Sandstone. The unit underlies a thick Upper Cretaceous section that contains bentonitic beds and uraniferous marine black shale. Water samples from the Dakota Sandstone aquifer contain as much as 122 parts per billion Uranium-3 Oxygen-8. Geologic units considered unfavorable include most of the Paleozoic rocks, except in the Brandon Fault area; the Upper Cretaceous rocks; and the Ogallala Formation. The Dockum Group, Morrison Formation, and Lytle Member of the Purgatoire Formation are unevaluated because of lack of data.

From Introduction: "The La Junta Quadrangle, Colorado and Kansas (Fig. 1), was evaluated to identify and delineate areas and geologic units to a depth of 1500 m (5,000 ft) that exhibit characteristics favorable for the occurrence of uranium deposits, which could contain at least 100 tons U3O8 and have an average grade of not less than 100 ppm U3O8."

From abstract: Results of a reconnaissance geochemical survey of the Lincoln Quadrangle are reported. Field and laboratory data are presented for 577 groundwater and 754 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From abstract: Results of a reconnaissance geochemical survey of the Grand Island Quadrangle, Nebraska; Kansas are reported. Statistical data and areal distributions for uranium and uranium-related variables are presented for 564 groundwater and 532 stream sediment samples. Also included is a brief discussion on location and geologic setting.

This report presents the results of analyses of the airborne gamma radiation and total magnetic field survey flown for the Scott City quadrangle in Kansas.
