MACROFLORAL ANALYSIS OF BULK SEDIMENT SAMPLES TO IDENTIFY CHARRED REMAINS SUITABLE FOR AMS RADIOCARBON DATING FROM ANTELOPE VALLEY NEAR TOPAZ LAKE, CALIFORNIA-NEVADA BORDER

Bulk soil samples from paleoseismic trenches were examined to recover charred
material suitable for AMS radiocarbon dating. These trenches were excavated across the active
fault bounding the west side of Antelope Valley near Topaz Lake along the California-Nevada
border. Botanic components and detrital charcoal were identified, and potentially radiocarbon
datable material was separated.

对采自古地震探槽的批量土壤样品开展检测，以提取适用于加速器质谱（AMS）放射性碳定年的炭化物质。这些探槽开挖于加利福尼亚州与内华达州边境附近托帕兹湖周边、羚羊谷西侧的活动断裂带之上。研究人员识别出植物组分与碎屑炭，并分离出具备放射性碳定年潜力的样品。
