POLLEN/STARCH, MACROFLORAL, CHARCOAL IDENTIFICATION, AND PROTEIN RESIDUE ANALYSIS AT SITES 32ME258, 32ME263, 32ME264, 32ME266, 32ME717, AND 32ME1261 IN THE FREEDOM MINE AREA 2 NORTH, WESTERN NORTH DAKOTA

Samples from six sites in the Freedom Mine Area 2 North, Mercer County, North
Dakota, were submitted for pollen/starch, macrofloral, charcoal identification, and/or protein
residue analyses. These six sites contain stone rings and are believed to represent habitation
sites. Pollen and/or macrofloral analysis of hearth fill samples from sites 32ME264 and
32ME717 will be used to provide information concerning plant resources utilized by the
prehistoric occupants of these sites. Charcoal samples from sites 32ME263, 32ME717, and
32ME1261 were submitted for identification prior to radiocarbon dating. Lithic artifacts from five
of the six sites were analyzed for possible protein residues.

采自美国北达科他州（North Dakota）默瑟县（Mercer County）自由矿区2北区（Freedom Mine Area 2 North）6处遗址的样本，已提交开展花粉/淀粉粒、大植物遗存、炭质遗存鉴定及/或蛋白质残留物分析。该6处遗址均发现石质环迹，被推断为史前居住遗址。针对遗址32ME264与32ME717的灶坑堆积样本开展的花粉及/或大植物遗存分析，将为揭示该两处遗址史前居住者所利用的植物资源情况提供依据。来自遗址32ME263、32ME717及32ME1261的炭质遗存样本，已在放射性碳定年（radiocarbon dating）前完成送检鉴定。该6处遗址中5处出土的石器遗存（Lithic artifacts），已针对其是否含有蛋白质残留物开展检测分析。
