Evidence for tectonic movement of the Las Positas Fault, Alameda County, California Evidence for tectonic movement of the Las Positas Fault, Alameda County, California
On October 29, 1979, a new exposure of the Las Positas fault zone near Livermore, California, was created by excavation of a creek bank along Arroyo Seco. The face of the bank was cleaned by geologists of Lawrence Livermore Laboratory (Livermore, California) to obtain a better and more complete view of the fault. The excavation was undertaken by Lawrence Livermore Laboratory as part of a...

Base and precious metal occurrences along the San Andreas Fault, Point Delgada, California Base and precious metal occurrences along the San Andreas Fault, Point Delgada, California
Previously unrecognized veins containing lead, zinc, and copper sulfide minerals at Point Delgada, Calif., are associated with late Mesozoic(?) and Tertiary volcanic and sedimentary rocks of the Franciscan assemblage. Sulfide minerals include pyrite, sphalerite, galena, and minor chalcopyrite, and galena-rich samples contain substantial amounts of silver. These minerals occur in a quartz...

Neogene basin formation in relation to plate tectonic evolution of San Andreas fault system, California Neogene basin formation in relation to plate tectonic evolution of San Andreas fault system, California
More than 90% of the known petroleum accumulations west of the San Andreas fault in California are in strata deposited in areally restricted Neogene basins that formed during a major tectonic reorganization of western California. These deep, localized Neogene basins replaced broad, regionally persistent Paleogene depositional aprons, although some of the Neogene basins in northern and...
