Geophysical Investigations at Pahute Mesa, Nevada

Abstract

Part 1 of this study has concentrated on the assembly of a data base of geological and geophysical data for a transect at Pahute Mesa, Nevada. Existing data, in the form of well logs, gravity observations and seismic travel times, have been supplemented by new gravity and seismic data especially for the construction of a geophysical model of the shallow crust. The transect is modeled as an extension basin, with up to 5 km of structural relief and volcanic fill. Major faulting is on the east side. The second part of this study has applied the new GPS technology to geogetic monitoring of nuclear explosions at Pahute Mesa, Nevada. Significant deformation is observed to be caused by the test BULLION. New rapid survey methods have been successfully applied to perform studies, which would have been otherwise prohibitively time consuming.
