PHYTOLITH AND MACROFLORAL ANALYSIS AND AMS RADIOCARBON DATING OF SAMPLES FROM LA 175601, LEA COUNTY, NEW MEXICO

Site LA 175601, located along Salado Draw in Lea County, New Mexico, is a short-term plant processing site believed to have been used to procure plant resources locally. Fill from two thermal features were submitted for phytolith and macrofloral analyses to address questions of resource processing. Charcoal recovered from the macrofloral samples was submitted for AMS radiocarbon dating. Results from the phytolith and macrofloral analyses, as well as radiocarbon dates, will be applied to the greater understanding of landscape adaptation and settlement patterns in southeast New Mexico.

坐落于新墨西哥州利县（Lea County）萨拉多德莱夫溪（Salado Draw）沿岸的LA 175601遗址，为一处短期植物加工遗址，推测其功能为就地采集并加工植物资源。研究人员采集了两处热遗迹（thermal features）的填积物，送检开展植硅体（phytolith）与大植物遗存（macrofloral）分析，以厘清植物资源加工相关的科学问题。从大植物遗存样本中提取的炭屑则被送检，用于加速器质谱碳十四定年（AMS radiocarbon dating）。植硅体与大植物遗存分析结果，连同加速器质谱碳十四定年数据，将为深化新墨西哥州东南部的景观适应与聚落模式研究提供关键支撑。
