POLLEN, STARCH, AND BLOOD RESIDUE ANALYSIS OF GROUNDSTONE FROM SITES IN LANDER COUNTY, NEVADA

Groundstone from six sites in central Nevada were examined for pollen, starch granules, and possible blood residues. Pollen and blood residue analyses address subsistence at these sites. Pollen analysis was undertaken on manos, metates, and groundstone fragments, while blood residue analysis was performed only on mortars and pestles. Pollen recovered from the ground surfaces may provide information concerning plants ground using manos and metates. Immunological studies have shown that blood residues from a tool's surface can be identified using modified forensic procedures. Blood residue analysis may provide information concerning animals processed using mortars and pestles.对内华达州中部6处遗址出土的研磨石器开展了花粉、淀粉粒及疑似血液残留物的检测分析。花粉与血液残留物分析旨在探究这些遗址的生业模式。研究人员针对手磨石（manos）、磨盘（metates）以及研磨石器碎片开展了花粉分析，而血液残留物分析仅针对臼（mortar）与杵（pestle）进行。从研磨工具表面提取得到的花粉，可提供有关利用手磨石和磨盘加工的植物类群的相关信息。免疫学研究已证实，借助改良的法医检测程序，可对工具表面的血液残留物进行物种识别。血液残留物分析则可提供有关利用臼与杵加工的动物类群的相关信息。
