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.

This is an aerial reconnaissance survey report of the Delta Quadrangle in Utah.

From introduction: This study is part of the United States Department of Energy's National Uranium Resource Evaluation Program to understand the geologic setting, amount, and availability of uranium resources within the boundaries of the United States.

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.

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.

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.

From abstract: Twenty-two holes totaling 34,874 feet (10,629.6 meters) were rotary and core drilled on the northern and western flanks of the San Rafael Swell to test fluvial-lacustrine sequences of the Morrison Formation and the lower part of the Chinle Formation. The objective of the project was to obtain subsurface data so that improved uranium resource estimates could be determined for the area.

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.

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Salina 10 x 20 quadrangle. Surface sediment samples were collected at 1418 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Ground water samples were collected at 143 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.

From abstract: Results of the Marysvale detailed geochemical survey are reported. Field and laboratory data are presented for 397 stream sediment samples and 160 radiometric readings. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

Data collected as part of a report of Marysville, Utah including laboratory data on well water (pp. 1-3) and stream sediments (pp. 4-27) as well as field data (pp. 29-175).
