EXAMINATION OF BULK SOIL FROM A PALEOSEISMIC TRENCH ACROSS THE MERCUR FAULT, UTAH

Summary

Three bulk soil samples from a paleoseismic trench across the Mercur fault along the

eastern margin of the Great Basin in Utah were floated to recover organic fragments suitable for

radiocarbon dating. The trench transects a fault scarp on an alluvial fan surface estimated to

be at least 130,000 to 150,000 years old. Botanic components and detrital charcoal were

identified, and potentially radiocarbon datable material was separated.
