Geologic Framework of Jurassic Reservoir Rocks in the Dixie Valley Geothermal Field, Nevada: Implications from Hydrothermal Alteration and Stratigraphy

The main reservoir in the Dixie Valley geothermal field of Nevada is hosted in fractured Jurassic rocks within the hanging wall of the Stillwater fault. Within the Jurassic sequence, at least four major stages of alteration related to the fault system can be identified. The paragenetic sequence from oldest to youngest consists of Stage I) biotite-potassium feldspar veins, and epidote-chlorite-c...

Geologic Map of the Lahontan Mountains Quadrangle, Churchill County, Nevada

The Lahontan Mountains quadrangle is located 11 km east of Fallon, Nevada at the southeastern margin of the Carson Sink (Fig. 1). Principal physiographic features include the Lahontan Mountains, collectively consisting of Sehoo, Eetza, Salt Wells, and Rainbow mountains. This quadrangle is part of the greater Lake Lahontan area that in part occupied the southern Carson Desert, previously mapped ...

A Liquefaction Hazard Map of the Las Vegas Valley, Nevada

The potential for basin amplification of ground motion from significant seismic sources 100-200 km (62-124 mi.) from the Las Vegas Valley (such as the Death Valley Fault System) and Quaternary faults in the valley could provide sufficient energy to cause liquefaction. Key criteria of liquefiable soils coupled with a shallow groundwater table (less than 15 m (50 ft)) are met at several sites in ...

Description of Map Units for the Geologic Map of the Virginia City Quadrangle, Nevada

Qs Sand Wind-blown sand blankets a number of areas in the western part of the quadrangle. These well-sorted, mediumto fine-grained quartzose sands are commonly deposited on the east to northeast sides of hills but may extend across some flat areas. The sands are uncemented and loose but most are well stabilized by vegetation, locally including trees. The sands are usually white to tan but local...
