EXAMINATION OF BULK SOIL AND DETRITAL CHARCOAL, AND AMS RADIOCARBON AGE DETERMINATION OF MATERIALS FROM THE MINTO, DENALI, AND CASTLE MOUNTAIN FAULTS AND THE NORTHERN FOOTHILLS THRUST, ALASKA

Author(s): Peter Kováčik

Year: 2015

Summary

Six bulk soil samples from paleoseismic trenches across the Minto Fault, Denali Fault, and Castle Mountain Fault in Alaska were floated to recover and identify organic fragments suitable for radiocarbon age determination. In addition one macrofloral sample and eight detrital charcoal samples from a trench across the Northern Foothills Thrust (Alaska) also were submitted for identification. Botanic components and charcoal fragments were identified and potentially radiocarbon datable material was separated. Seven AMS radiocarbon dates were obtained on charcoal and charred botanic remains from these samples.
