Pollen, Phytolith, Macrofloral, and Charcoal Analyses in the Jewett Mine Project Area, Texas

Fossil pollen, phytoliths, macrofloral remains,
and charcoal from archaeological and geological sites
at the Jewett Mine, Texas are analyzed in this
appendix. Pollen analysis provides an overview of
regional vegetation and hence paleoenvironments for
this area. Pollen columns were collected at an
alluvial geological site in the Buffalo Creek floodplain
and at an archaeological site 4ILNI06, in the
Lambs Creek drainage for this reconstruction.
Companion phytolith samples were collected from
the same profiles, and they supply information
concerning the mixture of grasses within the local
prairie. Together the pollen and phytolith records
provide a look at both local and regional vegetation
in the project area. Several samples were collected
from the present ground surface to evaluate the
modem pollen and phytolith records relative to
present vegetation.

本附录对美国德克萨斯州（Texas）朱伊特矿（Jewett Mine）考古与地质遗址出土的化石花粉、植硅体（phytoliths）、大植物遗存以及木炭开展分析。花粉分析可阐明区域植被概况，借此反演该区域的古环境。为完成本次古环境重建，研究团队分别于布法罗溪（Buffalo Creek）漫滩的冲积地质遗址，以及兰布斯溪（Lambs Creek）流域的考古遗址4ILNI06采集了花粉柱样。配套植硅体样品采自与花粉柱样相同的剖面，可提供有关当地草原内草本植物组成的相关信息。花粉与植硅体两类记录相结合，可全面展现研究区域内的局地与区域植被状况。此外，为评估现代花粉与植硅体记录与当前植被的对应关系，研究团队从当前地表采集了多份样品以供验证。
