Results from several years of an on-going mapping program in the Coyote Mountain at a scale of 1:2,000 shows the following: 1). Active left-lateral faulting and reactivation of older faults in a right-lateral environment; 2). Landslides and several terraces associated with the uplift of the Coyote Mountains; 3). Pliocene marine and non-marine transgressions and regressions; 4). Cenozoic thrust and detachment faults; 5). Miocene volcanic plugs, and U/Pb dated tuffs (17 Ma); 6). Cretaceous and Jurassic plutonic rocks; 7). Folding and faulting of metamorphosed Paleozoic and Mesozoic rocks, containing, marbles, schists, meta-cherts and amphibolites with meta-pillow-basalts.
