This 27-page report analyzes new detailed (1:12,000 scale) geologic mapping of a 14 square mile area centered by the high-temperature (350°F) Sulphurdale heat source, which at the surface makes up a circular area about a mile in diameter that is likely caused by a magma body at depth. A former small steam-driven geothermal electric power plant in the circular area is being replaced by a larger plant (Enel Green Power North America) that will use binary technology. Five cross sections tied to and at the same scale as the map help interpret the likely extent of the geothermal resource. Sulfur derived from evaporites at depth was initially mined at a solfatara above the heat source; associated sulfuric acid seeped downward to remove the Kaibab Limestone and Toroweap Formation from the subsurface.

This 23 page report is an initial investigation into the role that low-angle faulting may play in the formation of the Thermo Hot Springs Known Geothermal Area (KGRA), within the Sevier geothermal anomaly of southwestern Utah. The stratigraphy and structures exposed in the southern mineral mountains are used as an analog for studying the subsurface stratigraphy and the detachment fault within the Thermo Hot Springs KGRA.

Past exploration in low- and moderate-temperature systems of the Great Basin shows that the relatively small area associated with fluid upflow and elevated temperatures is often difficult to detect by drilling widely spaced temperature-gradient holes or by other methods. By studying the Newcastle geothermal system, we hoped to develop a basic understanding of the concealed hydrothemlal system as a tool for assessing other geothermal areas of the Great Basin. The emphasis of our work centered on determining (1) the distribution of subsurface heat and the movement of thermal fluid, (2) the location and geometry of bedrock structures that might control fluid movements, (3) the chemical character of the geothermal water, and (4) the geometry of the bedrock beneath the Escalante Desert. Field studies included: (1) drilling and monitoring temperatures in shallow themlal-gradient boreholes, (2) mapping geologic units and performing structural studies in the adjacent mountains, (3) conducting detailed gravity surveys, (4) conducting electrical resistivity and self-potential (SP) surveys, (5) collecting water samples for detennining major ions and light stable isotope analyses, and (6) mapping Quaternary units.

This CD contains a 63 p. report of the task force to identify and promote the development of renewable energy resources to meet the goal of 20 percent of Utah's electrical retail sales by 2025. Work groups were established to identify energy zones for wind, solar, and geothermal energy resources. The Phase I report identifies energy zones (approx. 13,262 sq. miles) and an estimated 837 gigawatts of electrical generating capacity.

This report describes the geology of the central Virgin River basin in southwestern Utah, and characterizes the structure and lithology of the Jurassic Navajo Sandstone and the thickness and stratigraphy of Quaternary-late Tertiary unconsolidated deposits, the two main aquifers in the region. Southwestern Utah has experienced rapid population growth and increased demand on water supplies during the past 15 years, and the purpose of this report is to better define the ground-water resources of the area. Ground water provides approximately half of the public water supply in southwestern Utah, so future decisions regarding water use must be based on careful geologic characterization of the aquifers and their relation to the regional hydrologic system. The results of this study will be applied to ground-water modeling, evaluating regional and local hydrogeologic conditions, and assessing sites for development of ground water. 53 pages + 7 plates

This report describes the nongeothermal hydrogeologic system of the Cove Creek basin and an adjoining part of the Beaver River basin north of Milford, in Millard and Beaver Counties, Utah. The groundwater system in the study area hosts two commercial geothermal reservoirs, provides the entire agricultural and culinary water supply, and may be connected with groundwater in adjoining basins. The report presents a regional hydrogeologic framework assessment, including a newly compiled 1:100,000-scale geologic map, five schematic cross sections, estimates of thickness and hydrologic character of the basin fill based on geophysics and available well logs, and a new potentiometric surface map for the study area. The report also presents and interprets new and compiled geochemical and isotopic data and a new water budget for the study area that includes estimates of subsurface flow to adjoining basins. 65 pages + 2 plates

"The Markagunt and Sevier gravity slides are gigantic landslides that resulted from gravitationally induced catastrophic failure of the southern flank of the Oligocene to Miocene Marysvale volcanic field. Each is nearly 100 km long with runouts over the former land surface >35 km; together they span 7000 km2 and rank among Earth's largest terrestrial landslides. Basal cataclastic layers, injectites, pseudotachylyte, deformed clasts, and a variety of kinematic indicators demonstrate catastrophic emplacement, which was preceded by slow gravitational spreading of the volcanic field. This volume offers a history of their discovery, our current understanding of the gravity slides, and a guide to particularly instructive exposures for which the authors document their conclusions about the size, age, and significant structural features of these newly discovered features"--

A bibliography of Utah geothermal references through 1984. These references which directly pertain to a geothermal resources are annotated. The annotations are intended to inform the reader of the information contained in the article, not to summarize the results. Accompanying the bibliography is a list and description of geothermal projects and commercial geothermal developments in Utah from 1966 to the present that have been wholly or partially funded through Federal or State programs. The references listed in the project descriptions are keyed to the bibliography. Most of this work is by government agencies or universities. Private or industry-funded geothermal developments are not listed. The references are indexed geographically either under 1.) United States (national studies), 2.) regional – western United States or physiographic province, 3.) Utah – statewide and regional, or 4.) county. Reports concerning a particular hot spring or thermal area are listed under both the thermal area and the county names.
