POLLEN, MACROFLORAL, AND ORGANIC RESIDUE ANALYSIS, AND AMS RADIOCARBON DATES FOR SAMPLES FROM SITE LA 126455, ROSWELL, NEW MEXICO

Fill from seven hearth features at site LA126455 in Roswell, Chaves County, southeast
New Mexico were examined for pollen and macrofloral remains. Fire cracked rock from one of
the hearths was examined for organic residues using Fourier Transform Infrared Spectroscopy
(FTIR). After identification, samples of charcoal from these hearths was radiocarbon dated.
Macrofloral, pollen, and organic residue analysis will be used to provide subsistence information
concerning plant resources utilized by the prehistoric occupants of the site.

对美国新墨西哥州东南部查维斯县罗斯韦尔的LA126455遗址的7处火塘遗存的填充堆积物，开展了孢粉与大植物遗存分析。选取其中一处火塘的火烧碎岩，采用傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy，FTIR）对其有机残留物进行检测分析。经鉴定后，对这些火塘中的木炭样品完成了放射性碳定年。本研究将通过大植物遗存、孢粉与有机残留物分析，揭示该遗址史前先民所利用的植物资源相关的生计信息。
