From Introduction: "The Cody NTMS Quadrangle, Wyoming, was evaluated to identify and delineate environments, rock units, and geographic areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Richfield 1º x 2º Quadrangle (Fig. 1), Utah, was evaluated to identify and delineate areas and geologic areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. A favorable area or environment, according to the specifications used in this study, is one that is known or is likely to have uranium deposits containing a minimum of 100 tons of U3O8 with an average grade of not less than 100 ppm U3O8."

From Purpose and Scope: "The Gillette 1º x 2º Quadrangle, Wyoming, and South Dakota was evaluated to find volumes of rock considered favorable for uranium deposits and which could contain at least at 100 mt tons U3O8 with an average grade of 0.01 percent U3O8 or more. All geologic environments to a depth of 1,500 m (5,000 ft) evaluated through the use of surface investigations and subsurface information."

From Purpose and Scope of Study: "The Torrington 1ºx2º Quadrangle in southeastern Wyoming and a small area of westernmost Nebraska was evaluated to determine areas favorable for the occurrence of uranium deposits. Geologic environments (areally or stratigraphically restricted parts of a geologic unit) were placed in categories of favorable, unfavorable, or unevaluated."

From Introduction Purpose and Scope: "The Arminto 1º x 2º quadrangle, in central Wyoming (Fig. 1), was evaluated to identify geologic environments that exhibit characteristics favorable for uranium deposition. Evaluation, consisting of three separate and distinct phases, started in October 1978 and ended in March 1980. It must be emphasized that this report is meant to be a preliminary reconnaissance-type study to identify favorable environments, as defined above."

From Introduction: "The Rawlins Quadrangle (2º) is in south-central Wyoming and extreme northwest Colorado (Fig. 1). Evaluation of the quadrangle was conducted to identify and delineate areas that contain environments exhibiting characteristics common to known uranium-bearing environments."

From Introduction: "The Casper NTMS 1º x 2º Quadrangle, Wyoming (Fig. 1), was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Formation and environments were evaluated for uranium favorability to a depth of 1500 m by surface and subsurface studies."

From Introduction: "The Lander Quadrangle, Wyoming (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Favorable areas are those that are capable of containing uranium deposit of at least 100 tons of U3O8 in rocks with a minimum average ore grade of 0.01%."

From Abstract: "The Ashton Quadrangle, Idaho, Montana, and Wyoming, was evaluated to identify and delineate areas containing environments favorable for uranium deposits, using criteria developed for the National Uranium Resource Evaluation program. Aerial radiometric data were evaluated, and anomalies were examined in the field. Fourteen uranium occurrences were noted in the study area."

From Introduction: "The Thermopolis Quadrangle (1º x 2º), Wyoming, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments and formations were evaluated to a depth of 1500 m from surface and subsurface investigations. Areas and environments were categorized as favorable, unfavorable, or unevaluated for uranium deposits."

From Introduction: "The Sheridan NTMS 1º by 2º Quadrangle (Fig. 1) in north-central Wyoming was evaluated to identify geologic environments that have characteristics favorable for uranium deposition. Only environments to a depth of 1500 m have been evaluated for this project."

Uranium resources of the Newcastle 1°x2° Quadrangle, Wyoming and South Dakota were evaluated to a depth of 1,500 m (5000 ft) using available surface and subsurface geologic information. Many of the uranium occurrences reported in the literature and in reports of the U.S. Atomic Energy Commission were located, sampled and described. Areas of anomalous radioactivity, interpreted from an aerial radiometric survey, were outlined. Areas favorable for uranium deposits in the subsurface were evaluated using gamma-ray logs. Based on surface and subsurface data, two areas have been delineated which are underlain by rocks deemed favorable as hosts for uranium deposits. One of these is underlain by rocks that contain fluvial arkosic facies in the Wasatch and Fort Union Formations of Tertiary age; the other is underlain by rocks containing fluvial quartzose sandstone facies of the Inyan Kara Group of Early Cretaceous age. Unfavorable environments characterize all rock units of Tertiary age above the Wasatch Formation, all rock units of Cretaceous age above the Inyan Kara Group, and most rock units of Mesozoic and Paleozoic age below the Inyan Kara Group. Unfavorable environments characterize all rock units of Cretaceous age above the Inyan Kara Group, and all rock units of Mesozoic and …
