CHARCOAL IDENTIFICATION AND AMS RADIOCARBON DATING OF SAMPLES FROM SITE SAR 1, BEXAR COUNTY, TEXAS

Three samples of sediment containing charcoal flecks were submitted for extraction of charcoal, charcoal identification, and AMS radiocarbon dating. These samples were recovered from Late Holocene alluvial deposits of the San Antonio River, Texas. Two of the samples yielded charcoal in sufficient quantities for AMS radiocarbon dating.

三份含有炭屑的沉积物样品被提交，用于炭质物提取、炭屑鉴定以及加速器质谱（AMS，Accelerator Mass Spectrometry）放射性碳定年。上述样品采自美国得克萨斯州圣安东尼奥河的全新世晚期冲积沉积层。其中两份样品的炭屑含量充足，可开展加速器质谱放射性碳定年。
