High-Angle Faults in the Basement of Yucca Flats, Nevada Test Site, Nevada, based on Analysis of a Constrained Gravity Inversion Surface

By Geoffrey A. Phelps and Edwin H. McKee

Thumbnail of and link to report PDF (10.4 MB)Abstract

Using a model of the topographic subsurface derived from drill hole and gravity inversion analysis of the basement rocks in Yucca Flat, Nevada Test Site (NTS), Nevada, a fault map and digital fault dataset were constructed based on offsets of the basement surface. Because these faults are, in large part, not present at the surface, they are interpreted to be inactive faults, older than the alluvial basin fill.
