Info
High-angle faults in the basement of Yucca Flats, Nevada Test Site, Nevada, based on analysis of a constrained gravity inversion surface

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.
