One sediment sample from the Shishaldin volcano on the Aleutian Islands (Site 18jrssh024) and four sediment samples from the Makushin volcano on the Eastern Unalaska Island (Site 18mkjrs001), Alaska were submitted for recovery of datable particulate organics and AMS radiocarbon age determination.
EXAMINATION OF BULK SOIL, MICROCHARCOAL EXTRACTION, AND AMS RADIOCARBON AGE DETERMINATION OF SAMPLES FROM THE DRUM MOUNTAINS PALEOSEISMIC TRENCH, MILLARD COUNTY, UTAH (2016)
The Drum Mountains Paleoseismic Trench lies approximately 5–10 km west of Delta in Millard County, Utah. Two bulk soil samples collected from colluvial wedge (fault) deposits in a paleoseismic trench were submitted for macrofloral analysis. Botanic components including charcoal were identified, and potentially radiocarbon datable material was separated. In addition, microscopic charcoal recovery and AMS radiocarbon age determination was requested for both samples.
