County Geologic Reports: Piute and Garfield Counties


Book Description

Two out-of-print geologic and mineral assessment reports on Piute and Garfield Counties are reproduced on CD in PDF format. Texts with plates are in one file for easy viewing; plates are a higher resolution and formatted for easy plotting are in separate files. Data contained in the reports must be viewed in light of their publication date and constraints of the period; some geologic units have been reclassified, some resource potentials have been drastically altered by changing economic/availability changes, etc. The publications on this CD are listed below: B-102 Mineral resource potential of Piute County, Utah and adjoining area, by E. Callaghan, 1973 B-107 Geology and mineral resources of Garfield County, Utah, by H. H. Doelling, 1975




Geologic and Hydrologic Characterization of Regional Nongeothermal Groundwater Resources in the Cove Fort Area, Millard and Beaver Counties, Utah


Book Description

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




Geology of the Sulphurdale geothermal-resource area, Beaver and Millard Counties, Utah


Book Description

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.

Geology of Utah's Mountains, Peaks, and Plateaus


Book Description

Utah’s landscape is among the most spectacular in the world. It is a region of prominent peaks, sweeping valleys, dramatic canyons, and plateaus rimmed by sheer cliffs. Unique among western states, Utah’s landscape includes the Colorado Plateau, Basin and Range, and Rocky Mountains geologic provinces. Exposed rocks tell the geologic story of the region’s basement structures, overlying surface features, and rock sequences that have contributed to sculpting the appearance of today's landscape. Rocks and formations record the evolution of the western part of the North American continent, and give clues to the nature of ancient crustal basement and Earth’s deeper layers. Climate change has shaped the present landscape through the erosional power of ancient glaciers and the presence of today’s large lakes and basins. Geology of Utah introduces the state’s deep earth, plate tectonics, and the development of its ancient mountains. It describes the geology of the three main geological provinces, ancient elevations, cliffs, valleys, and the history of the region’s climate. This book will enrich the experience of enthusiastic amateur geologists who want to understand and explore the development of Utah's highlands and the history of this dynamic landscape.
