... in extension direction resulted in the formation of ENE-oriented grabens. The Beowawe geothermal field is located in one of these ENE-oriented grabens that is bounded on the west by the NNW-trending, east-dipping Muleshoe fault ( John et al., 2000 ) and on the east by the NNW-trending, west-dipping Dunphy Pass...

... flow low ( Blackwell, 1983 ; Fig. 2 ). Next, we present a more local model of the present-day Beowawe geothermal field, which incorporates a series of subvertical, highly permeable faults connected to each other through a thin (~40 m), highly permeable aquifer within the Paleozoic carbonate unit...

...., 2014 ). Person et al. (2008) suggested that the Beowawe geothermal field in central Nevada has been active over perhaps the last ∼200 k.y., and evidence suggests that circulation can persist for as long as several million years for some systems (e.g., Casaceli et al., 1986 ; Nordquist and Delwiche...

Little or no steam-heated acid-sulfate alteration is present, probably the result of a near-surface water table during hydrothermal alteration and ore deposition. Two...

...) Betze-Post gold deposit had a maximum duration of <15 to 45 ka. The average gold flux over this period was ~80 to 30 kg yr −1 , comparable to that measured in the deep reservoirs of several modern geothermal fields. Conservative estimates of gold concentration in the main ore-stage fluids imply...
