Summary

Fault-slip data were collected from an area of relatively young faulting in a seismically active part of the Nevada Test Site 12 km NW of Mercury, Nevada. The data come primarily from intensely faulted Miocene tuffaceous sedimentary rocks in Hampel Wash, which is bounded on the north by the Quaternary ENE trending Rock Valley fault and on the south by a parallel unnamed fault. Analysis of the data using a least squares iterative inversion to determine a mean deviatoric principal stress tensor indicates a normal-faulting stress regime (S1 vertical) with principal stress axes in approximately horizontal and vertical directions (S1, trend = N19oE and plunge = 82oN; S2,, N30oE and 8oS; and S3, N60oW and 2oE). The N60oW least horizontal [...]
