| Abstract | The Beowawe geothermal systems appears to be a typical Basin and Range fault related hydrothermal system. The near surface geophysical expression of the convective Beowawe geothermal system is a zone of resistivities less than 10 ohm meters and an asymmetrical dipolar self potential anomaly of over 500 millivolts. Large velocity contrasts within the volcanic section produce unusable 1000% CDPS high resolution seismic reflection data. A widespread conductor at roughly three kilometers depth and influence of a major crustal conductor assorted with the NNW striking Oregon-Nevada lineament dominate the regional magnetotelluric response. Self potential and seismic emission data indicate poor permeability in the shallow part of the major fault plane southwest of the surface geothermal manifestations. |
