POLLEN, MACROFLORAL, AMS RADIOCARBON DATING, AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITE LA 32882, EDDY COUNTY, NEW MEXICO

Fill samples from a hearth and three midden features at site LA 32882 in southeastern New Mexico were examined for pollen and macrofloral remains. An El Paso brownware sherd from one of the midden features also was examined for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). This site is a long-term seasonal camp, and recovery of two brownware ceramic sherds indicate that the area was utilized by the Jornada Mogollon (AD 200-1400). The various analyses are used to gain information regarding diet, specifically plants that might have been processed, as well as general insight into the local vegetation. Charcoal samples from the feature fill were submitted for AMS radiocarbon dating to providetemporal information on site occupation. A total of four radiocarbon dates were obtained.

针对新墨西哥州东南部LA 32882遗址的一处火塘与三处食渣堆遗迹的填充堆积样本，开展了花粉与大植物遗存检测。其中一处食渣堆遗迹出土的埃尔帕索棕陶残片，亦通过傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy, FTIR）分析了有机残留物。该遗址属于长期季节性营地，出土的两件棕陶残片表明，这片区域曾被霍兰达莫戈隆文化（Jornada Mogollon，公元200年—1400年）的人群所利用。本研究通过各项分析，旨在获取与先民饮食相关的信息——尤其是可能被加工处理的植物种类，同时也为当地古植被状况提供一般性认知。遗迹填充层中的木炭样本被送检以开展加速器质谱碳十四测年（AMS radiocarbon dating），从而获取遗址使用的年代学信息。本次研究共获得4组碳十四测年数据。
