Report: Geophysical Study of Basin-Range Structure Dixie Valley Region, Nevada

Abstract
The study aims to determine the subsurface structure and origin ofa tectonically active part of the Basin and Range province, which hasstructural similarities to the ocean ridge system and to continental blockfaultstructure such_;s the Rift Valleys of East Africa. A variety oftechniques was utilized, including seismic refraction, gravity measurements,magnetic measurements, photogeologic mapping, strain analysis of existinggeodetic data, and elevation measurements on shorelines of ancient lakes.Dixie Valley contains more than 10,000 feet of Cenozoic deposits andis underlain by a complex fault trough concealed within the main graben.The bounding faults, studied by side refractions, are markedly crooked instrike and comparatively constant in dip. Dip-slip motion predominates.The computed strain energy is comparable to the energy derived from themagnitudes of the 1954 earthquakes. Ancient beach ridges record a maximum14 feet of westward tilting in approximately the last 10,000 years; thevalley has been subsiding with little net tilting.
