EXTRACTION OF MICROCHARCOAL AND AMS RADIOCARBON DATING OF SAMPLES FROM FORT SAGE SOUTH PALEOSEISMIC TRENCH, CALIFORNIA (2009)

DOCUMENT Full-Text Kathryn Puseman. Linda Scott Cummings.

Sediment samples were collected from a trench across an active normal fault in the Fort Sage Mountains in northeast California with the purpose of gaining insight into earthquake activity. These sediment samples were examined to recover organic material suitable for AMS radiocarbon dating. No macroscopic charcoal or other organic fragments were noted in these samples; therefore, they were processed to recover microscopic charcoal fragments (microcharcoal) for dating. Two of the samples yielded...
