MACROFLORAL ANALYSIS OF FILL FROM FEATURE 1, SITE 39PE147, SHADEHILL RESERVOIR, PERKINS COUNTY, SOUTH DAKOTA

The floated light fraction of a single sample from site 39PE147, located at the Shadehill
Reservoir, Perkins County, South Dakota, was examined for macrofloral remains. The sample
was recovered from the fill of a large pit (Feature 1), possibly an earth oven. The entire feature
fill was floated prior to submission for analysis. Macrofloral analysis is used to provide
information concerning plant resources utilized by the occupants of this site and to help
determine feature function.

本研究针对采自美国南达科他州帕金斯县沙德希尔水库遗址39PE147的单份样品的浮选轻组分，开展了大植物遗存（macrofloral remains）检测分析。该样品出土于一处大型坑穴（1号遗迹）的堆积层中，该遗迹可能为土灶。该遗迹的全部堆积在送交分析前均经过了浮选处理。大植物遗存分析可用于获取该遗址先民所利用的植物资源相关信息，并辅助判定该遗迹的功能。
