Report issued by the Bureau of Mines over studies conducted on the zinc-lead deposits in Cherokee County, Kansas. As stated in the introduction, "the purpose of this report is to present the factual data derived from both the preliminary examination and the subsequent field work." (p. 3). This report includes tables, and maps.

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.

Appendices containing data on uranium occurrences and analyses from the Lamar Quadrangle, in addition to petrographic descriptions of samples.
