Summary: "The potential impacts to visual resources, resulting from construction and operation of a nuclear waste repository and transportation route in the Gibson Dome Area of southeastern Utah, were evaluated."

The primary objective of this project was to enhance domestic petroleum production by field demonstration and technology transfer of an advanced-oil-recovery technology in the Paradox Basin, southeastern Utah. If this project can demonstrate technical and economic feasibility, the technique can be applied to approximately 100 additional small fields in the Paradox Basin alone, and result in increased recovery of 150 to 200 million barrels (23,850,000-31,800,000 m3) of oil. This project was designed to characterize five shallow-shelf carbonate reservoirs in the Pennsylvanian (Desmoinesian) Paradox Formation and choose the best candidate for a pilot demonstration project for either a waterflood or carbon-dioxide-(CO2-) miscible flood project. The field demonstration, monitoring of field performance, and associated validation activities will take place within the Navajo Nation, San Juan County, Utah.

This contains a geological map and index map of quadrangles for the Colorado plateau area.

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).

Supplementary data containing locations of uranium deposits in the Brushy Basin project area, Utah and Colorado.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Ogden and Salt Lake City quadrangles including results of data interpretation, significance factor profile maps, stacked profiles, and histograms.

A report discussing exploratory diamond drilling in the Posey and Markey localities.

Results obtained from a program designed to locate a low- or moderate-temperature geothermal resource that might exist beneath Hill Air Force Base (AFB), Ogden, Utah are discussed. A phased exploration program was conducted at Hill AFB. Published geological, geochemical, and geophysical reports on the area were examined, regional exploration was conducted, and two thermal gradient holes were drilled. This program demonstrated that thermal waters are not present in the shallow subsurface at this site. (MHR)

Abstract: Uranium was discovered on the Silver King claims in the fall of 1953. The claims are on the west flank of the Sheeprock Mountains in the eastern part of the Erickson mining district, Tooele County, Utah. Uraninite occurs in north- to northwest-trending copper-nickel-silver bearing fissure veins near the margin of a granitic stock of probable late Tertiary age. Sedimentary rocks in contact with the granite are chiefly dolomite and quartzite of Middle and Upper Ordovician age. Diamond drilling on this property did not disclose significant amounts of uranium; however, encouraging showings have been found by underground exploration by the owner.

The following report covers the study of electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting.

This report follows a 12-hole drilling program that was conducted on the northwestern flank of the San Rafael swell of eastern Utah.

From introduction: This report contains the results of a detailed geological and uranium deposits study made of the Monument Valley.

Abstract: The Happy Jack uranium deposit of White Carron, San Juan County, Utah, was studied in connection with an Atomic Energy Commission exploration program. The major uranium ore control is a paleostream channel containing sediments of the Shinarump conglomerate. Intrachannel controls include organic matter, lithologic variations, and channel "lows". Microscopic studies reveal that uraninite, the primary ore mineral, occurs as cement and as a replacement of organic material. Both the uraninite and copper sulfides replace secondary quartz overgrowths. Crystals of chalcopyrite, chalcocite, and pyrite occur one within the other. Resolution of bornite and chalcopyrite is present. Uraninite is dated as later than the secondary overgrowths and of about the same age as the copper sulfides.

Report discussing the geology of the Red House Cliffs area, which comprises 296 square miles of canyon and plateau country in southwestern San Juan County, Utah.

Gregory described the broad geologic and geographic features of the white canyon area in the reconnaissance report on San Juan county.

Report discussing the exploration of the uranium ore-containing ancient channels of the Shinarump member of the Chinle formation of Late Triassic age through the use of a refraction seismograph.

Introduction: This study was made in conjunction with a core drilling program designed to trace ore trends from existing mines eastward under deeper cover. The exploration drilling covered an area of about 1 square mile. The results of previous drilling by the Commission, which covered an additional 10 square miles, have been incorporated in this report.
