Geophysical framework of the southwestern Nevada volcanic field and hydrogeologic implications
V.J. Grauch, David A. Sawyer, Chris J. Fridrich, Mark R. Hudson
1999, Professional Paper 1608
Gravity and magnetic data, when integrated with other geophysical, geological, and rock-property data, provide a regional framework to view the subsurface geology in the southwestern Nevada volcanic field. The region has been loosely divided into six domains based on structural style and overall geophysical character. For each domain, the subsurface...
