CERAMIC AND ORGANIC RESIDUE (FTIR) ANALYSIS ON CERAMICS AND PROTEIN ANALYSIS ON A BIFACE FROM SITE DLLG 33, MANITOBA, CANADA

Four ceramic rimsherds from site DlLg 33, a prehistoric riverine trade loci, located in downtown Winnipeg, Manitoba, Canada, were submitted for ceramic and organic residue analysis. In addition, a single biface was examined for protein residue. Ceramics were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Ceramic and organic residue analyses on the ceramics will be used to provide information regarding the foods processed in the vessels and their origins, and perhaps, shed light on decorative influences, beyond style types.本次研究送检了加拿大曼尼托巴省温尼伯市中心史前河岸贸易遗址DlLg 33出土的4件陶器口沿残片，用于开展陶器与有机残留物分析。此外，还对1件双面打制石器进行了蛋白质残留物检测。研究采用傅里叶变换红外光谱法（Fourier Transform Infrared Spectroscopy, FTIR）对陶器样品的有机残留物进行测试。本次陶器分析与有机残留物检测结果，将用于明确这些陶容器曾加工处理的食物种类及其来源，或还可阐释除器物形制类型之外的装饰风格影响因素。
