"This report represents the results of the reconnaissance sampling of the Deep Creek Mountains of western Utah...Samples collected in this study include dry and wet stream sediments and water from available streams, wells, and springs. The samples were analyzed for uranium, as well as 15 to 20 trace element, using neutron activation techniques. In addition, field and laboratory measurements were made on the water samples."

Uranium deposits in the precambrian quartz-pebble deposits of the Raft River area in northwestern Utah and southcentral Idaho are examined. A total of 1214 geochemical samples were acquired for the study, particularly 334 water samples, 616 stream sediment samples, and 264 rocks.

From abstract: Results of an ERDA-sponsored, high-sensitivity, airborne gamma-ray spectrometer and magnetometer survey of a portion of the Delta, Utah, NTMS, 1:250,000 scale quadrangle, carried out under Bendix Field Engineering Corporation Subcontract 76-019-L are discussed. The objective of the survey was to evaluate the Delta area as a uraniferous province, i.e., a region showing surface indications of a generally higher uranium content, and evidence of geochemical uranium enrichment over the other natural radioactive elements, where detailed exploration for uranium would likely be successful. The known presence of late stage Tertiary rhyolites and granites associated with fluorite and uranium occurrences and one productive uranium mine strongly suggested that the area is such a uraniferous province. A DC-3 aircraft equipped with a gamma-ray spectrometer using nine large-volume NaI detectors, two 400 channel analyzers, and ancillary geophysical and electronic equipment was employed for data collection.

Second volume of a report on aerial gamma-ray and magnetic survey of the Delta area of Utah, containing illustrations such as histograms, anomaly maps at a reduced scale of 1:500,000, and magnetic profiles related to the survey.

Purpose and scope: The purpose of this study was to delineate new areas favorable for uranium exploration in the San Rafael Swell region of east-central Utah. Emphasis was placed on the sandstone and siltstone members of the lower Chinle Formation (Triassic) and on the Salt Wash and Brushy Basin Members of the Morrison Formation (Jurassic). The White Rim Sandstone (Permian) was also studied, but not extensively. This project began in January 1976 and was completed in March 1977. Field work was conducted during the five-month period from February through June 1976.

This report is a preliminary evaluation of the uranium resources of the Brushy Basin Member of the Morrison Formation of Late Jurassic age in southwestern Colorado and southeastern Utah. The project, which began July 1, 1976, and was completed October 1, 1976, was carried out by the Bendix Field Engineering Corporation (BFEC) for the Grand Junction Office of the U.S. Energy Research and Development Administration (ERDA).

From approach: This survey consisted of aerial gamma-ray spectrometer and magnet-meter data collection including: (1) Coverage of those portions of the Delta, Utah NTMS 1:250,000 scale quadrangle (Figure 1-1) which were not surveyed in 1976 under Bendix Field Engineering Corporation subcontract No. 76-019-L, Texas Instruments (1977a). (2) Reflights of portions of the 1976 flight lines which were out of altitude specifications. (3) Extra flight lines over the 1976 survey area to provide complete detailed coverage of the NW quarter of the quadrangle. The program also included processing and interpretation of the gamma-ray spectrometer data necessary to indicate potential new uranium prospecting areas.
