POLLEN, PHYTOLITH, STARCH, PROTEIN, AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM THE RIVER ROAD SITE (36BU0379), PENNSYLVANIA

The River Road Site (36BU0379) in Bucks County, Pennsylvania, was occupied by Late Woodland people. Sediment samples from a midden, a living surface, and stratigraphic stratum were submitted for pollen analysis to provide information concerning the past environment. In addition, artifacts and soil control samples were submitted for pollen, phytolith, starch, protein residue, or organic residue analyses specifically to provide subsistence information. Organic residues samples were examined using Fourier Transform Infrared Spectroscopy (FTIR). Sediment samples from a midden deposit and a buried living surface also were examined for pollen to provide subsistence information concerning plant resources utilized by the Late Woodland occupants of this site. Organic residue, phytolith, and starch analyses of ceramic sherds were performed to identify materials contained in the ceramic vessels, while analysis of organic residues removed from a pipe bowl was undertaken to identify materials smoked using this pipe. Pollen, phytolith, starch, and protein residue analyses of stone/lithic artifacts can provide information concerning plant resources processed and animal resources that were processed and/or hunted using these tools.

宾夕法尼亚州巴克斯县的河路遗址（36BU0379）曾为伍德兰晚期先民的定居点。为获取该区域过去的环境信息，研究人员采集了贝丘、生活面及地层的沉积物样本开展孢粉分析。此外，研究人员还提交了人工制品与土壤对照样本，针对性开展孢粉、植硅体、淀粉、蛋白质残留物及有机残留物分析，以获取古代生计相关信息。有机残留物样本通过傅里叶变换红外光谱（Fourier Transform Infrared Spectroscopy，FTIR）进行检测。贝丘沉积物与埋藏生活面的沉积物样本亦接受了孢粉分析，以明确该遗址伍德兰晚期定居者所利用的植物资源相关的生计信息。对陶片开展有机残留物、植硅体与淀粉分析，可识别陶瓷容器内的承载物质；同时对从烟斗碗中提取的有机残留物进行分析，以确定该烟斗所熏制的物品。对石/石器制品开展孢粉、植硅体、淀粉与蛋白质残留物分析，则可获取有关这些工具所加工的植物资源，以及经其加工或狩猎获取的动物资源的相关信息。
