EXAMINATION OF BULK SOIL AND AMS RADIOCARBON ANALYSIS OF MATERIAL FROM THE DUTCHMAN DRAW TRENCH SITE ON THE WASHINGTON FAULT, ARIZONA

Author(s): Kathryn Puseman

Year: 2009

Summary

A total of four bulk soil samples from the Dutchman Draw Trench site on the

Washington Fault in northwest Arizona were examined to recover organic fragments suitable

for radiocarbon analysis. These samples were recovered from soil stringers in the PE wedge,

as well as from paleosol beneath the Most Recent Event (MRE) wedge in the North

paleoseismic trench. Botanic components and detrital charcoal were identified, and potentially

radiocarbon datable material was separated. Two of the samples did not yield sufficient

macroscopic charcoal for dating; therefore, they were processed to recover microscopic

charcoal to obtain a radiocarbon date.
