STARCH, ORGANIC RESIDUE (FTIR) ANALYSIS, AND AMS RADIOCARBON DATING OF A CERAMIC SHERD FROM CANYON FERRY LAKE, LEWIS AND CLARK COUNTY, MONTANA

A ceramic vessel rim sherd recovered from Canyon Ferry Lake in Lewis and Clark County, Montana was submitted for starch, organic residue analysis, and AMS radiocarbon dating. The ceramic was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR).

从蒙大拿州刘易斯与克拉克县（Lewis and Clark County）的峡谷渡湖（Canyon Ferry Lake）采集的一件陶瓷容器口沿残片，被送检以开展淀粉粒分析、有机残留物分析以及加速器质谱（AMS）放射性碳定年。该陶瓷样品采用傅里叶变换红外光谱（FTIR）技术对有机残留物进行了检测。
