Geologic evolution and regional implications of southern Old Dad Mountain, Mojave Desert, California
Olson A, Andrew J, Walker D. Geologic evolution and regional implications of southern Old Dad Mountain, Mojave Desert, California. Research Permit and Reporting System
New data from Old Dad Mountain finds 3 major structures: Early Cretaceous left-lateral Powerline Canyon Shear Zone; Late Cretaceous Playground Thrust, with top to the southeast transport; and Miocene Old Dad normal fault. Cross cutting relationships and kinematic data obtained in this study make it unlikely that a strand of the active dextral Soda-Avawatz Fault zone is present at Old Dad Mountain, but show obvious similarities between with the Clark and New York Mountains, to the east.
