This report describes the study made to define areas showing surface indications of a generally higher uranium content where detailed exploration for uranium would most likely be successful in the Trinidad quadrangle.

Second volume of data from a radiometric and magnetic reconnaissance survey of the Trinidad quadrangle in Colorado, including "Results of the interpretation in the form of a preferred anomaly map, along with significance-factor profile maps stacked profiles, histograms, and descriptions of the geology and known uranium occurrences" (vol. 1, p. 1).

From purpose and scope: The purpose of this study is to identify and delineate areas favorable for the occurrence of uranium deposits "which could contain at least 100 metric tons of U308 with an average grade of not less than 100 ppm U308". The study was limited to depths of less than 1500 m (5000 ft). No attempt was made to make the economics of recovering uranium a criterion for selecting favorable areas, except that the uranium be in a "mineable configuration".

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.
