Tectonic Map of Western Nebraska and Northwestern Kansas Showing the Distribution of Uranium Occurrences
From introduction: The Cordilleran Foreland (King. 1951, p. 58-62; Horberg and others, 1949, p. 192194) forms a broad north-south belt, parallel to and east of the Cordilleran geanticline (fig. 1), in which the predominant geologic structure is a series of anticlinal mountains and broad asymmetric basins that contrast sharply with the folds and overthrusts related to the Cordilleran geanticline. 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.
