| Publisher Description: We present geochronologic and geochemical data for Mesozoic rocks in the Black Mountain area northeast of Victorville, California, to supplement previous geologic mapping. These data, together with previously publish results, lint the depositional age of the sedimentary Fairview Valley Formation to Early Jurassic, refine the ages and chemical compositions of selected units in the overlying Jurassic Sidewinder Volcanics and of related instructive unites, and limit the age of some post-Sidewinder faulting in the Black mountain area to a brief interval in the Late Jurassic. |
