EXAMINATION OF BULK SOIL FROM PALEOSEISMIC TRENCHES ACROSS THE HAYWARD FAULT AND THE SAN ANDREAS FAULT NEAR SAN FRANCISCO, CALIFORNIA

Author(s): Kathryn Puseman

Year: 2012

Summary

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 material in samples from the San Andreas Fault.
