PHYTOLITH, STARCH, AND PROTEIN RESIDUE ANALYSIS OF A BASALT MORTAR FROM SITE 45DO917, LOWER MOSES COULEE, DOUGLAS COUNTY, WASHINGTON

A large basalt mortar was submitted for phytolith, starch, and protein residue analyses from site 45DO917. This is a pre-contact site located on Lower Moses Coulee near Wenatchee, Washington. The goal of these analyses is to identify plant and animal resources that may have been processed using this mortar.

一件采自45DO917遗址的大型玄武岩臼（basalt mortar）被送检，用于开展植硅体（phytolith）、淀粉粒（starch）及蛋白质残留物（protein residue）分析。该遗址位于美国华盛顿州韦纳奇（Wenatchee）附近的下摩西谷（Lower Moses Coulee），属于前接触时期遗址。本次分析的核心目的为识别出可能曾通过该臼进行加工处理的动植物资源。
