POLLEN AND PHYTOLITH ANALYSIS OF A STAIN AT 41EN169, TEXAS

Pollen and phytolith samples were examined from an organic stain at 41RN169 in Runnels County, Texas in an effort to identify the origin of the stain. Control samples from unstained matrix were also examined for both pollen and phytoliths to establish a record with which to compare the data obtained from examination of the stain.为明确美国得克萨斯州伦宁县41RN169遗址处一处有机污渍的来源，本研究对该污渍中的花粉与植硅体（phytolith）样品开展了检测分析。同时，本研究还针对未受该污渍浸染的基质对照样品进行了花粉与植硅体检测，以建立可供比对污渍检测所得数据的参照数据集。
