Geology of the Cove Fort-Sulphurdale KGRA

Description: The Cove Fort-Sulphurdale Known Geothermal Resource Area (KGRA) is located on the northwestern margin of the Marysvale volcanic field in southwestern Utah. The geology of the KGRA is dominated by lava flows and ash-flow tuffs of late Oligocene to mid-Miocene age that were deposited on faulted sedimentary rocks of Paleozoic to Mesozoic age. The geothermal system of the Cove Fort-Sulphurdale KGRA is structurally controlled by normal faults. High-angle faults control fluid flow within the geotherm… more

Geochemistry and hydrothermal alteration at selected Utah hot springs. Final report: Volume 3 (revised)

Description: Application of Na-K-Ca geothermometry to warm springs in Utah indicates several areas with sufficiently high apparent temperatures to be of interest as geothermal exploration targets. A zone of warm springs in the Bonneville Basin show Na-K-Ca temperatures from 150/sup 0/C to 233/sup 0/C. Examination of Great Salt Lake, Bonneville sediment pore water, and Jordan Valley well-water chemistry indicates that mixing a small percent of these fluids with warm spring water can cause substantial errors … more

Assessment of radiological impact of the inactive uranium-mill tailings pile at Salt Lake City, Utah

Description: One of the largest inactive uranium mill tailings piles in the United States is located within metropolitan Salt Lake City, Utah. A radiological survey was performed at this site during the fall of 1975. A series of field and laboratory analyses were performed to characterize the spread of contamination from the tailings pile to surrounding areas. These analyses provided a basis for discussion of the important pathways for transport of radioactivity to man. Measurements of radionuclide concentr… more

Oxygen-isotope geochemistry of quaternary rhyolite from the Mineral Mountains, Utah, USA

Description: Oxygen isotope analyses were made of phenocryst and glass separates from four Quaternary rhyolite flows and domes in the Mineral Mountains, southwest Utah. With the exception of biotite in all samples and alkali feldspar in the rhyolite domes, all minerals appear to be in close oxygen isotope exchange equilibrium. The geothermometry equations proposed by Bottinga and Javoy (1973) and Javoy (1977) for quartz, alkali feldspar and magnetite produce the best agreement with temperature results fom t… more
