A single bulk sediment sample from along the Blacksmith Fork near Hyrum, Utah, was floated to recover organic fragments suitable for radiocarbon analysis. The sample was recovered from fluvial deposits in a soil pit on a late Holocene river terrace. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated.
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...
