IDENTIFICATION OF CHARCOAL FROM BULK SEDIMENTS ALONG THE CARSON RIVER IN NORTHERN NEVADA AND EASTERN CALIFORNIA

Bulk soil samples were recovered from deposits along the Carson River in northern Nevada and eastern California for a paleoflood study. The sediments were floated to recover charcoal and other organic remains suitable for radiocarbon dating. Botanic remains, including charcoal, were identified and radiocarbon datable materials were separated.为开展古洪水（paleoflood）研究，研究人员从内华达州北部与加利福尼亚州东部的卡森河（Carson River）沿岸沉积物中采集了散装土壤样本。对获取的沉积物进行浮选处理，以提取可用于放射性碳定年的木炭及其他有机遗存。研究人员对包括木炭在内的植物遗存进行了鉴定，并分离出可用于放射性碳定年的材料。
