Download or read book Geology and Mineral Potential of the Antelope Range Mining District Iron County Utah written by Michael A. Shubat and published by Utah Geological Survey. This book was released on 1988 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antelope Range mining district, located approximately 20 miles (32 km) west of Cedar City, Utah, contains many occurrences of epithermal, base and precious metals mineralized veins. Host rocks in the district range from limestone of the Carmel Formation through a sequence of Tertiary ash-flow tuffs. Neogene extensional faulting produced northwest-striking structures that host mineralized veins. The mineralization and hydrothermal alteration is approximately 8.5 Ma. Ore and gangue minerals show a paragenetic sequence that consists of an earlier base metals stage followed by a later silver sulfosalt stage. Maximum precious metal values from vein samples are 9 oz/ ton silver and 0.22 oz/ton gold. Factor analysis results of geochemical data independently corroborate the paragenetic sequence. Both lateral and vertical geochemical zonations are inferred. Mineralization is interpreted to be the product of a boiling hydrothermal system induced by rhyolitic and dacitic volcanism. Potential exists for the discovery of silver-bearing epithermal vein deposits. 26 pages + 2 plates

Download or read book A Case Study of the Newcastle Geothermal System Iron County Utah written by Robert E. Blackett and published by . This book was released on 1992 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Selected Mining Districts of Utah written by Carl L. Ege and published by Utah Geological Survey. This book was released on 2005 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.
