POLLEN AND PHYTOLITH ANALYSIS FOR SITES 33LE396 AND 33LE405, OHIO

Stratigraphic samples were examined for both pollen and phytoliths from two archaeological sites (33Le396 and 33Le405) to identify vegetation and changes in vegetation that can provide information concerning paleoenvironmental conditions. Features at site 33Le405 yielded radiocarbon ages indicating Early to Late Woodland occupations, whereas site 33Le396 appears to have been occupied during the Middle Woodland. Feature samples were examined for pollen and phytoliths from each of these site to provide information concerning possible plant processing.本研究对两处考古遗址（33Le396与33Le405）的地层样品开展花粉与植硅体（phytoliths）分析，以明确植被组成及其变化特征，进而获取古环境相关研究信息。经检测，33Le405遗址的考古遗迹遗存的碳十四测年结果显示，其人类活动时段涵盖早伍德兰期至晚伍德兰期；而33Le396遗址的人类活动则集中于中伍德兰期。此外，本研究还对两处遗址的各考古遗迹样品开展花粉与植硅体分析，以获取与古人类植物加工行为相关的信息。
