ANALYSIS OF C-14 CHARCOAL AND MACROBOTANICAL REMAINS FROM THE DIXIE VALLEY AREA, NEVADA

Bulk soil samples were recovered from fluvial stream terrace deposits and an alluvial fan near Dixie Valley, Nevada. The area is located approximately 50 to 75 miles east of the Carson Sink. The fluvial stream is perennial and drains nearby mountain ranges. Mountain ranges in vicinity of the study area include the Stillwater Range and the Clan Alpine Range. Botanic materials and detrital charcoal were identified in very limited quantities from the stream terrace deposits, and potentially radiocarbon datable materials were separated.本研究从美国内华达州迪克西谷（Dixie Valley）附近的河流阶地沉积与冲积扇中采集了批量土壤样本。该区域大致位于卡森洼地（Carson Sink）以东约50至75英里处。研究区内的河流为常年性河流，其流域涵盖周边山脉。研究区域周边的山脉包括斯蒂尔沃特山脉（Stillwater Range）与克兰阿尔卑斯山脉（Clan Alpine Range）。在河流阶地沉积中仅检出极少量植物材料与碎屑炭，并分离出潜在可进行放射性碳定年（radiocarbon dating）的样品。
