PROTEIN AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITES EFOO 134, EFOO 180, AND EJOP 29, ALBERTA, CANADA

Hearth fill and fire-broken rock from sites EfOo 180, EfOo 134, and EjOp 29, Alberta, Canada, were submitted for organic residue analysis. Samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Five lithic tools from these sites also were analyzed for protein residues. Protein and organic residue analysis provide information regarding diet, specifically materials processed using lithic tools and thermal features, respectively, at these sites.

本研究对加拿大阿尔伯塔省EfOo 180、EfOo 134与EjOp 29遗址出土的炉坑堆积物及火烧破裂岩石进行送检，以开展有机残留物分析。研究采用傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy, FTIR）对上述样品实施有机残留物检测。此外，本研究还针对上述遗址出土的5件石制工具开展了蛋白质残留物分析。蛋白质残留物与有机残留物分析可分别为该批遗址的饮食相关研究提供信息：前者可反映石制工具所加工的物料类型，后者则可体现热活动遗迹的相关遗存特征。
