V.E. Langenheim R.C. Jachens G. A. Phelps 1999 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 2,500 m in the deepest, southern part of the basin. The model shows offsets in the basement rocks along both the Carpetbag and Yucca faults. The basement rocks of Yucca Flat have a higher gravity anomaly west of the N-S trending Carpetbag fault, suggesting higher density rocks on the west side of the valley. application/pdf 10.3133/ofr99310 en U.S. Geological Survey Thickness of Cenozoic Deposits of Yucca Flat Inferred from Gravity Data, Nevada Test Site, Nevada reports
