CERAMIC AND ORGANIC RESIDUE (FTIR) ANALYSIS, AND AMS DATING OF CERAMIC SHERDS FROM A SINGLE VESSEL AT SITE 11PK1791/1792, PIKE COUNTY, ILLINOIS

Thirteen ceramic sherds, representing a single Late Woodland vessel from site
11PK1791/1792, were submitted for ceramic (pollen, phytolith, starch) and organic residue
analysis to determine the contents of the vessel. One sherd was selected as the best candidate
for each analysis. Organic residue was examined using Fourier Transform Infrared
Spectroscopy (FITR). Residue removed from the sherds was examined for pollen, phytoliths,
and starch, as well as AMS radiocarbon dating.

本次研究针对遗址11PK1791/1792出土的1件晚伍德兰期（Late Woodland）陶器的13块陶片开展检测，旨在明确该陶器的内含物，检测项目包括陶瓷类分析（孢粉、植硅体、淀粉粒分析）与有机残留物分析。针对每一项检测，均选取1块最优陶片作为检测样品。其中有机残留物采用傅里叶变换红外光谱法（Fourier Transform Infrared Spectroscopy，FITR）进行检测。此外，研究人员还对从陶片上提取的残留物开展孢粉、植硅体、淀粉粒检测，并完成加速器质谱放射性碳定年（AMS Radiocarbon Dating）。
