Abstract

Some of the results from several years of geological mapping of the Coyote Mountains, an on-going geological project, show the following: 1). Active left-lateral faulting and reactivation of older faults in a right-lateral stress field, 2). Landslides and several terraces associated with the uplift of the Coyote Mountains; 3). Pliocene Imperial Group marine transgressions and regression with non-marine sediments, 4) Fresh water limestones (Bouse Formation equivalent?), 5). New interpretation of the Garnet Formation in relationship with the Imperial Group; 6). Cenozoic thrust and detachment faults; 7). Miocene volcanic plug and cinder cones with dated tuffs(17 +/-2Ma); 8). Cretaceous and Jurassic igneous dated rocks; 9). Folded and faulted metamorphic rocks made up of: marbles, schists, gneisses, banned cherts, cherts, quartzites and amphibolites with pillow basalts.
