1999, Open-File Report 99-310
The basin-basement contact for Yucca Flat was modeled using isostatic gravity data, a linear density-depth function for the basin deposits, and drill-hole constraints to produce a digital database of both the depth to basement and the gravitational anomaly associated with the basement rocks. The model predicts a depth of roughly...

1997, Open-File Report 96-599
Analysis of water collected during August and September 1993 from well PM-2, on Pahute Mesa at\x11the Nevada Test Site, indicated tritium concentrations of\x1121,000 Bq/L at 610 m below land surface. The Schooner event (U-20u) was detonated in 1968 approximately 270 meterssoutheast of well PM-2 at a working...

Paleozoic strata on the Nevada Test Site and surrounding area are affected by the intersection of several important geologic trends, including the early Paleozoic rift margin and the Late Devonian-Early Mississippian Antler orogenic foredeep. Upper Paleozoic strata are lithologically diverse and include siliciclastic sediments (carbonaceous shale, clean quartzose sands, bedded...
