IDENTIFICATION AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES BIBE 1859, BIBE 1910, AND BIBE 1942 IN BIG BEND NATIONAL PARK, TEXAS

Charcoal and charred corn cobs from sites BIBE 1859, BIBE 1910, and BIBE 1942 in Big Bend National Park, Texas, were submitted for identification and AMS radiocarbon dating. Site BIBE 1859 is a prehistoric open campsite, while sites BIBE1910 and BIBE 1942 are prehistoric sites with historic components. AMS radiocarbon dates were obtained on four charcoal samples and two charred corn cobs.

采自美国得克萨斯州大弯曲国家公园内BIBE 1859、BIBE 1910及BIBE 1942三处遗址的木炭与炭化玉米芯样本，被送检用于植物物种鉴定与加速器质谱（Accelerator Mass Spectrometry，AMS）放射性碳测年。其中BIBE 1859为史前露天营地遗址，BIBE 1910与BIBE 1942则为兼具历史遗存组分的史前遗址。本次研究共从四份木炭样品与两份炭化玉米芯样本中获取了加速器质谱放射性碳测年数据。
