Appendices containing data on uranium availability to accompany a report on U.S. uranium resources in the Durango Quandragle, Colorado.

From purpose and study: The Durango Quadrangle, southwest Colorado (Fig. 1), was evaluated to identify geologic units and to delineate areas that exhibit characteristics favorable for uranium deposits. Geologic environments were evaluated to a depth of 1500 m based on recognition criteria (Mickle and Mathews, eds., 1978) prepared for the National Uranium Resource Evaluation (NURE) program. A favorable environment, as defined for this program, is an environment that could contain at least 100 tons U308 in deposits with an average grade no less than 100 ppm U308 . Environments that did not meet the NURE criteria were categorized as unfavorable. Some of the subsurface and several areas of restricted access were categorized as unevaluated because insufficient data exist for proper evaluation.

From Summary: "Within the gross content of economic exploration techniques developed through case studies of know mineralization, this report of research into the Spokane Mountain uranium deposit integrates the results of numerous field surveys and the application of proven scientific methods with the effects of alternative methods."

A report discussing the Owens Valley Drilling project, with the goal of obtaining subsurface data relevant to the Coso Formation that would permit more reliable estimates of the uranium resources potential of the project and adjacent areas.

From Introduction: "The Trinidad Quadrangle, Colorado, was evaluated to identify geologic units and to delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments were evaluated by means of surface investigations and subsurface data to a depth of 1500 m."

Report describes the structural and stratigraphic framework, depositional environment, and petrology and petrography of the various Pennsylvanian-Permian time and rock units present in Oklahoma. This report identifies five geologic settings favorable for the localization of uranium, such as alluvial fan deposits, oil-productive structures where Permian sandstones are altered, tidal-flat sandstone-silstones, channel sandstones on gentle structural features, and oil-productive Cherokee sandstones.

Appendices containing data on uranium availability in the Beeville Quadrangle to accompany a report of U.S. uranium resources in Texas.

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".

Supplementary maps documenting data from the Bozeman Quadrangle. From text: "The Bozeman Quadrangle is south-central Montana was evaluated for geologic environments capable of containing uranium deposits to a depth of 1500 m (5,000 ft.). Most rock types and geographic areas were investigated by surface traverse, and hydrgeochemical data were collected from available well sites."

Appendices containing supplementary analytical data of uranium occurrences, chemical analyses of stream-sediment, rock, and soil samples, and tabulated radiometric and gamma-ray anomaly data to accompany a report on U.S uranium resources in the Leadville Quadrangle, Colorado.

From Purpose: "The White Sulphur Springs Quadrangle, in west-central Montana between latitude 46º and 47ºN. and longitude 110º and 112ºW. (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Favorable environments, as determined by surface and subsurface investigations, are those that could contain uranium deposits of at least 100 tons U3O8 at an average not less than 100 ppm U3O8."

From Introduction: "The Front Range region from the Wyoming-Colorado state line to southern Colorado is a uranium metallogenic province. Correspondingly, uranium has been discovered in mineable deposits in metamorphic, igneous, and sedimentary rocks formed throughout the geologic history of the region both within the Front Range itself and in the apron of sedimentary rocks that surrounds the Front Range. The Pueblo 1ºx2º National Topographic Map Series (NTMS) quadrangle, Colorado (Fig. 1), which lies within this uranium metallogenic providence, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits."
