Archaeological Pollen Analyses from North-central Wisconsin

Study of 30 surface and 18 archaeological-context pollen samples was undertaken to assess the potential for further archaeological palynology research. Surface sample analysis allows palynological recognition of eight habitat types ranging from dry and cold through wet and moist to dry and warm. Comparison of fossil and modern surface pollen data suggests the character of paleoecological change sequences at 4 sites, a positive potential for inter-site and intra-site relative cross-dating, and a positive potential for inter-regional dating on paleoclimatic grounds.

本研究针对30份地表样品与18份考古背景花粉样品展开分析，旨在评估开展后续考古孢粉学（archaeological palynology）研究的潜力。地表样品分析可实现8类生境类型的孢粉学识别，涵盖从干冷、湿润潮湿至干暖的多种生境。通过对比化石花粉与现代地表花粉数据，可明确4处遗址的古生态变化序列特征，同时展现出遗址间与遗址内部开展相对交叉定年的良好潜力，以及基于古气候依据实现跨区域定年的积极前景。
