From introduction: This report, one of a series of three reports (Marjaniemi and Robins, 1975a and 1975b) on a study of Tertiary sedimentary rocks in northeastern Washington, presents the results of an investigation of Tertiary sediments of the western Okanogan highlands and upper Columbia River valley. The project was conducted on behalf of the Energy Research and Development Administration (ERDA), formerly the U. S. Atomic Energy Commission.

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.

From addendum: Two types of analyses for uranium in the stream-sediment samples are presented. One split of the stream-sediment samples was sent to Resource Associates of Alaska's laboratory, where they were analyzed for U by the fluormetric method after acid extraction. This is the method employed for U by most laboratories. The completeness of uranium extraction unavoidably varies with the particular type of uranium-bearing minerals present and possibly with the amount of iron, manganese, and carbonaceous material present, which can interfere with the extraction. Analyses by the method are shown in the text and appendix columns with the designation "RAA."

This is a set of 62 plates that accompany a report on uranium favorability in rocks of the south Texas coastal plain.

From purpose and scope: The objective of this study was to delineate areas of maximum uranium favorability in Tertiary sediments that underlie part of the South Texas Coastal Plain.

From 1995 sites in the San Juan Mountains area, 1706 water and 1982 sediment samples were collected during June-July 1976 and analyzed for uranium. The area includes the southern third of the Colorado mineral belt which has yielded rich ores of gold, silver, copper, lead, zinc, and molybdenum. The broadly domed mountains are capped by 2500 m of Tertiary volcanics, deeply eroded to expose a Precambrian crystalline core. Adjacent plateaus underlain by Mesozoic sedimentary rocks were included in the reconnaissance. Average value of uranium in water samples from mountains was less than 0.5 parts per billion, from plateaus was 1-2 parts per billion, from Mancos shale areas exceeded 2 parts per billion. Anomalous sediment samples, 40 ppm uranium, came from near Storm King Mountain and upper Vallecito Creek. Other anomalous areas, including the Lake City mining district, were well defined by 4-30 parts per million uranium in sediment and 3-30 parts per billion uranium in water. Anomalous areas not previously reported indicate favorable areas for future exploration.

The following report discusses the study of radioelements in precambrian rock samples taken from the upper peninsula of Michigan and northern Wisconsin.

From objectives: This report demonstrates the concept of hydrogeochemical sampling to be used in the 12-state region for which UCC-ND has the responsibility if surveying as part of the NURE. The results of a geochemical survey at two sample spacings in the Crystal City Quadrangle in south Texas are presented.

Data collected as part of a uranium geochemical survey in the Crystal City and Beeville Quadrangles in Texas including laboratory data stream sediments and water, well water, and botanical samples for phase 1 (pp. 1-8); for phase 2 including the same with lake samples (pp 9-36); well water samples only for phase G (p. 37); and field data for all phases (pp. 38-374).

From introduction: This report presents the results of a preliminary study of uranium occurrences in the beryllium belt of Juab County, Utah. The study was conducted by Bendix Field Engineering Corporation (BFEC) for the U.S. Energy Research and Development Administration (ERDA) to aid in estimating the uranium potential of the area.

Supplementary data containing geologic and sample site maps of Juab County to accompany a report on U.S. uranium resources in Utah.

From purpose and scope: The purpose of this project was to determine the uranium favorability of Mesozoic intrusive rocks and Tertiary volcanic and sedimentary rocks in the central Mojave Desert. The project was conducted by Bendix Field Engineering Corporation (BFEC) under the auspices of the Grand Junction Office of the U.S. Energy Research and Development Administration (ERDA). The scope of the project included determination of the uranium content of different rock types, determination of the nature and extent of rock characteristics favorable for the formation of uranium deposits, and examination of known uranium deposits.

From introduction: This report presents data gathered in a Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) conducted by the Los Alamos Scientific Laboratory (LASL) in southwestern Montana. The HSSR was initiated by the US Department of Energy (DOE) to outline areas favorable for uranium exploration by examining uranium concentrations in natural waters and stream sediments.
