Considering a lack of recent volcanism, the abundant geothermal
activity in the northwestern Great Basin is somewhat
anomalous.  The prolific activity may result from enhanced
dilation on N- to NNE-striking normal faults induced by a
transfer of NW-directed dextral shear from the Walker Lane
to NW-directed extension in the Great Basin.  Although faults
control most geothermal activity in the Great Basin, few
detailed investigations have been conducted on the specific
structural controls of individual fields.  Because knowledge of
such structures would facilitate exploration models, we have
embarked upon a regional study of the controls on geothermal
activity, which includes detailed analysis of several fields,
reconnaissance studies of many other fields, and compilation
of existing data.  Our findings from the Bradys, Desert Peak,
Needle Rocks, Salt Wells, and Gerlach geothermal systems
suggest that many fields occupy discrete steps in fault zones
or lie in belts of intersecting, overlapping, and/or terminating
faults.  In addition, most fields are associated with steeply
dipping faults and, in many cases, with Quaternary faults.  The
structural settings favoring geothermal activity all involve
subvertical conduits of highly fractured rock along fault zones
oriented approximately perpendicular to the least principal
stress.  Features indicative of these settings that may be helpful
in guiding exploration include: 1) major steps in range-fronts,
2) interbasinal highs, 3) mountain ranges consisting of relatively
low, discontinuous ridges, and 4) lateral terminations of mountain ranges.
