MACROFLORAL ANALYSIS OF A SINGLE SAMPLE FROM SITE 32GT241 AT THE HEART BUTTE RESERVOIR, NORTH DAKOTA

A single sample from a small hearth at site 32GT241 on the Heart River in Grant County, southwest North Dakota, was examined for macrofloral remains. Wood charcoal from this site yielded a conventional radiocarbon age of 2560 ± 30 years B.P, indicating a Late Plains Archaic occupation. Macrofloral analysis of the hearth fill is used to provide information concerning plant resources that might have been processed in the hearth and types of wood burned as fuel.针对北达科他州西南部格兰特县哈特河沿岸32GT241遗址一处小型火塘的单一样本，开展了大植物遗存（macrofloral remains）检测分析。该遗址出土的木炭经常规放射性碳定年，测得距今2560±30年的结果，表明此处曾有平原古风晚期（Late Plains Archaic）的人类居住活动。通过对该火塘填充物开展大植物遗存分析，可获取有关曾在火塘中加工的植物资源，以及作为燃料被燃烧的木材种类的相关信息。
