POLLEN, PHYTOLITH, MACROFLORAL ANALYSES, AND AMS RADIOCARBON DATING OF SAMPLES FROM A THERMAL FEATURE AT SITE LA 172823, EDDY COUNTY, NEW MEXICO

Seven samples from two levels of fill in a thermal feature at site LA 172823 in Eddy County, New Mexico, were analyzed for pollen, phytoliths, and macrofloral remains. Charcoal and charred botanic remains recovered from the macrofloral samples were submitted for AMS radiocarbon dating. A total of seven dates were obtained. This site consists of a single thermal feature and small scatter of prehistoric lithic artifacts. Pollen, phytolith, and macrofloral analyses will provide information concerning plant resources utilized by the site occupants, while radiocarbon dating will determine the time period for use of the feature.针对美国新墨西哥州埃迪县LA 172823遗址内一处热遗迹的两层堆积所获取的7份样品，开展了孢粉（pollen）、植硅体（phytoliths）与大植物遗存（macrofloral remains）分析。从大植物遗存样品中回收的炭屑与炭化植物标本，已提交进行加速器质谱（AMS）碳十四测年，共获得7组测年数据。该遗址仅包含一处热遗迹与一处小型史前石制品散布点。孢粉、植硅体与大植物遗存分析将为解析该遗址居民所利用的植物资源提供信息，而碳十四测年则可确定该热遗迹的使用年代区间。
