Cenozoic Tectonic Evolution Of The Central Wassuk Range, Western Nevada, Usa, Benjamin E. Surpless
Cenozoic Tectonic Evolution Of The Central Wassuk Range, Western Nevada, Usa, Benjamin E. Surpless
Geosciences Faculty Research
The central Wassuk Range of western Nevada is ideally located to investigate the interplay of Basin and Range extension and Walker Lane dextral deformation on the margin of the Basin and Range province. To elucidate the Cenozoic evolution of the range, the author conducted geologic mapping, structural data collection and analysis, geochemical analysis of igneous lithologies, and geochronology. This research delineates a three-stage deformational history for the range. A ~15 Ma pulse of ENE-WSW directed extension at high strain rates (~8.7 Ma) was immediately preceded by the eruption of andesites and was accommodated by high-angle, closely spaced (1-2 km), east-dipping …
