Book Geology  Ore Deposits  and History of the Big Cottonwood Mining District  Salt Lake County  Utah

Download or read book Geology Ore Deposits and History of the Big Cottonwood Mining District Salt Lake County Utah written by Laurence P. James and published by Utah Geological Survey. This book was released on 1979 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Big Cottonwood area lies in the highest portion of the Wasatch Mountains southeast of Salt Lake City. It contains exposed geologic features developed during two billion years of earth history. Discoveries of small but rich mineral deposits within the area led to a colorful, moderately productive, century-long period of metal mining. While there is no mining activity in the Big Cottonwood mining district today, the area is of considerable interest to students of regional geology and to numerous visitors to the mountain recreational areas. Major thrust faulting is well exposed in outcrops and in mine workings and is of economic importance on a regional scale. The unusual occurrence of the major ore bodies, at the intersections of steep fissure veins with several overthrust planes, similar to that of deposits mined in the adjoining Little Cottonwood (Alta) and American Fork districts to the south, is a classic regional feature. The small deposits in the older Precambrian rocks at the eastern edge of the district present features not seen elsewhere in the state. This report presents new detail on these and other aspects of the geology of the district, and records available geology and history of the many formerly-active underground mines. It presents an update on regional geology. It is written for readers of many interests, not merely for economic geologists. 98 pages + 4 plates

Book Engineering Geology of the Salt Lake City Metropolitan Area  Utah

Download or read book Engineering Geology of the Salt Lake City Metropolitan Area Utah written by William R. Lund and published by Utah Geological Survey. This book was released on 1990 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geologic exposures in the Salt Lake City region record a long history of sedimentation and tectonic activity extending back to the Precambrian Era. Today, the city lies above a deep, sediment-filled basin flanked by two uplifted range blocks, the Wasatch Range and the Oquirrh Mountains. The Wasatch Range is the easternmost expression of major Basin and Range extension in north-central Utah and is bounded on the west by the Wasatch fault zone (WFZ), a major zone of active normal faulting. During the late Pleistocene Epoch, the Salt Lake City region was dominated by a succession of inter-basin lakes. Lake Bonneville was the last and probably the largest of these lakes. By 11,000 yr BP, Lake Bonneville had receded to approximately the size of the present Great Salt Lake.
