IDENTIFICATION OF DETRITAL CHARCOAL AND CHARRED BOTANIC REMAINS, AND AMS RADIOCARBON AGE DETERMINATION OF MATERIAL COLLECTED ALONG LITTLE BEAR RIVER AND THE EAST FORK OF LITTLE BEAR RIVER, UTAH

Twenty-six detrital charcoal samples and one botanic sample were examined to recover organic fragments suitable for radiocarbon age determination. These samples were collected from Holocene terraces along Little Bear River and the East Fork of Little Bear River, a tributary to the Little Bear River, near the towns of Hyrum and Paradise in northeastern Utah. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A total of eight radiocarbon dates were obtained on charcoal and one charred botanic item recovered from these samples.

本研究对26份碎屑炭（detrital charcoal）样品与1份植物标本开展检测，以提取适用于放射性碳年代测定的有机碎片。上述样品采自美国犹他州东北部海勒姆（Hyrum）与帕拉迪斯（Paradise）镇附近的小熊河（Little Bear River）及其支流东叉小熊河（East Fork of Little Bear River）沿岸的全新世阶地。研究人员对样品中的植物组分与碎屑炭进行了鉴定，并分离出具备放射性碳测年潜力的材料。最终，从这批样品回收的炭质材料中，共计获得8组炭屑放射性碳年代数据，以及1件炭化植物遗存的测年结果。
