POLLEN, PHYTOLITH, MACROFLORAL, PROTEIN, AND ORGANIC RESIDUE ANALYSES; CHARCOAL IDENTIFICATION; AND AMS RADIOCARBON DATING OF SAMPLES FROM THE DICKERSON STREET AND WATER WORKS SITES, NEW YORK

Samples from the Dickerson Street and Water Works sites north of Albany, New York, were submitted for pollen, phytolith, macrofloral, protein, and organic residue analysis, along with companion charcoal identification and AMS radiocarbon dating. Samples are to be examined in two stages. Selected samples are to be analyzed first, and preliminary results are to be reported to the client before beginning the analyses on the remainder of the samples. In stage one, sediments from the Dickerson Street site were selected for pollen and phytolith analysis, along with chert points for protein analysis and fire-cracked rock for organic residue
analysis. Sediments from the Water Works site were also chosen for pollen and phytolith analysis, in addition to being examined for botanical remains. Macrofloral analysis is planned for feature fill from this site, and materials are expected to be selected for AMS radiocarbon dating, along with identified charcoal samples. Lithic tools also from the Water Works site were submitted for protein analysis, and fire-cracked rock and ceramics were submitted for organic residue analysis (FTIR).

本次研究的样品采自美国纽约州奥尔巴尼市北部的迪克森街（Dickerson Street）遗址与水厂（Water Works）遗址，已送交开展孢粉、植硅体、大植物遗存、蛋白质及有机残留物分析，并同步配套炭屑鉴定与加速器质谱碳十四测年（AMS radiocarbon dating）。所有样品将分两阶段完成检测：首先对筛选出的样品进行分析，在启动剩余样品的分析工作前，需向委托方提交初步分析结果。第一阶段中，本次研究选取迪克森街遗址的沉积物开展孢粉与植硅体分析，同时选取燧石尖状器进行蛋白质分析，火烧岩则用于有机残留物分析。水厂遗址的沉积物除用于植物遗存检测外，也被选取开展孢粉与植硅体分析。该遗址的遗迹充填物计划开展大植物遗存分析，相关材料将与已鉴定的炭屑样品一同被选取用于加速器质谱碳十四测年。水厂遗址出土的石制工具也被送交开展蛋白质分析，火烧岩与陶器则被送检有机残留物分析（傅里叶变换红外光谱，FTIR）。
