Geophysical maps and interpretations of the Domeland Wilderness and contiguous Roadless Areas, Kern and Tulare counties, California

Geophysical maps were compiled and constructed from gravity and aeromagnetic surveys of the study area in order to assist the geologic mapping and the mineral resource assessment of the Domeland Wilderness and contiguous roadless areas. The isostatic residual gravity map (fig. 1) primarily reflects lateral density variations within the upper crust beneath the region studied. The aeromagnetic map r

Index of faults of Cretaceous and Cenozoic age in the eastern United States

The information in this report was collected between 1974 and 1982 as part of the Reactor Hazards Program of the U.S. Geological Survey (USGS). This program was initiated to delineate and assess geologic hazards that could be particularly detrimental to major constructions, especially nuclear reactors. Faults are of principal interest to the program because earthquakes associated with them can cau
