MACROFLORAL ANALYSIS AND AMS RADIOCARBON DATING OF A HEARTH AT SITE 5RB5596, WESTERN COLORADO

The fill from a fire hearth at Site 5RB5596 in western Colorado was examined for macrofloral remains to provide subsistence information concerning plant resources utilized by the prehistoric occupants of this site. Charcoal from the hearth fill also was identified and processed for AMS radiocarbon analysis to identify woods burned as fuel and an age of occupation.研究人员对科罗拉多西部5RB5596遗址的火塘堆积进行了大植物遗存检测，以获取该遗址史前居住者所利用植物资源的生计相关信息。同时，研究人员还对火塘堆积中的木炭开展了物种鉴定，并进行加速器质谱（Accelerator Mass Spectrometry，简称AMS）放射性碳测年分析，以此明确作为燃料被燃烧的木材种类，以及该遗址的人类居住年代。
