Tectonic Map of Western South Dakota Showing the Distribution of Uranium Deposits

Description: From introduction: A tectonic map of most of the Cordilleran Foreland (fig. 2) is being compiled as an aid to study the geologic setting of uranium deposits within the region, and to determine what relationships may exist between the distribution of uranium deposits and the regional tectonic pattern (Osterwald, 1955). The map will show the distribution of faults, uranium deposits, areas of volcanic activity, and crestlines and troughs of folds.

Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota

Description: From introduction This report describes large-scale depositional units referred to as architectural elements, interpreted from outcrops of three distinct fluvial sandstone units of the Lakota Formation in the southwestern Black Hills area of Custer and Fall River Counties, South Dakota. These fluvial deposits formed near the end of an episode of continental deposition that began when the Jurassic Sundance sea regressed from the region and ended when the Early Cretaceous Skull Creek sea encroached from the north in Albian time.

A Two-Dimensional, Finite-Difference Model of the High Plains Aquifer in Southern South Dakota

Description: Purpose: The objectives of this study were (1) to collect, synthesize, and interpret geologic and hydrologic data on the aquifer in the southern South Dakota area; (2) to evaluate, by digital-computer-model simulation, values assigned to the aquifer parameters; and (3) to evaluate the sensitivity of the calibrated digital-computer-model to changes in magnitude of the selected hydrologic parameters. Results of this study are, therefore, applicable to solving potential water-resource management problems in the southern South Dakota and northern Nebraska model area.
