San Andreas Fault (Geographic Keyword)
1-7 (7 Records)
The Filoli paleoseismic site is located on the San Andreas Fault in Woodside, San Mateo County, California. Bulk soil samples collected from the north wall of Trench 2 and from the south and north walls of Trench 3 were submitted for macrofloral analysis to recover charred remains suitable for AMS radiocarbon age determination. One to four different charred remains from every sample were selected, yielding a total of 30 AMS radiocarbon dates.
EXAMINATION OF BULK SOIL AND AMS RADIOCARBON DATING OF MATERIAL FROM PALEOSEISMIC TRENCHES ACROSS THE BULNAY FAULT, MONGOLIA, AND THE SAN ANDREAS FAULT, CALIFORNIA (2010)
A total of six bulk soil samples from paleoseismic trenches were floated to recover organic fragments suitable for radiocarbon analysis. Three samples were recovered from the Bulnay Fault in northern Mongolia and from the San Andreas Fault in northern California. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A total of 11 AMS radiocarbon dates were obtained.
EXAMINATION OF BULK SOIL FROM PALEOSEISMIC TRENCHES ACROSS THE HAYWARD FAULT AND THE SAN ANDREAS FAULT NEAR SAN FRANCISCO, CALIFORNIA (2012)
A total of six bulk soil samples from paleoseismic trenches near San Francisco, California, were floated to recover organic fragments suitable for radiocarbon dating. Four samples were recovered from a trench across the Hayward Fault, while two samples were collected from a trench across the San Andreas Fault. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A total of eight AMS radiocarbon dates were obtained on charred...
EXAMINATION OF BULK SOIL FROM PALEOSEISMIC TRENCHES ACROSS THE SAN ANDREAS FAULT NEAR SAN FRANCISCO, CALIFORNIA (2012)
A total of ten bulk soil samples from paleoseismic trenches near San Francisco, California, were floated to recover organic fragments suitable for radiocarbon dating. Samples were collected from trenches across the San Andreas Fault at Crystal Springs South (11CSS). Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Eight radiocarbon dates were obtained.
EXAMINATION OF BULK SOIL SAMPLES FOR POTENTIAL RADIOCARBON DATABLE MATERIAL FROM THE ELIZABETH LAKE PALEOSEISMIC SITE, CALIFORNIA (2014)
The Elizabeth Lake site is located in the town of Elizabeth Lake, 18 miles northwest of Palmdale, California. Nine soil samples, collected from two paleoseismic trenches opened across the San Andreas Fault, were submitted to recover and identify material appropriate for AMS radiocarbon age determination. In addition, microcharcoal extraction was requested for three samples.
EXAMINATION OF BULK SOIL SAMPLES FOR POTENTIAL RADIOCARBON DATABLE MATERIAL FROM THE FRAZIER MOUNTAIN PALEOSEISMIC SITE, LOS ANGELES COUNTY, CALIFORNIA (2015)
The Frazier Mountain Paleoseismic Site is situated along the San Andreas Fault near Gorman, California. Two samples, collected from an alluvial fan on the northern slope of Frazier Mountain (Kate Scharer, personal communication June 17, 2015) were submitted for macrofloral analysis to recover and identify charred botanic remains and charcoal suitable for AMS radiocarbon age determination.
EXPLORATORY POLLEN ANALYSIS OF SEDIMENTS FROM THE FRAZIER MOUNTAIN PALEOSEISMIC SITE, CALIFORNIA (2012)
Six samples from a core collected in a closed depression along the San Andreas fault on the north flank of Frazier Mountain were selected for pollen analysis to examine the paleoenvironmental record. In addition, quantities of microscopic charcoal smaller than 250 microns were tabulated to provide preliminary information on fire history.
