Geophysical study of Cenozoic geologic structures of northern Owens Valley, California

A narrow gravity minimum anomaly of amplitude 30 mgals indicates that northern Owens Valley, California, a narrow fault-bounded trough or graben filled with Cenozoic clastic deposits to a depth of as much as 8,000 ft. Seismic-refraction measurements support this conclusion. Aeromagnetic and gravity measurements define a small, dense, and magnetic body buried by the valley fill of northern Owens Valley.
