POLLEN, PHYTOLITH, AND MACROFLORAL ANALYSES AT SITES 5SH1912, 5SH3386, 5SH3418, 5SH3439, 5SH3445, 5SH3484, AND 5SH3503, AND AMS RADIOCARBON DATING AT SITE 5SH3418, IN THE GREAT SAND DUNES NATIONAL PARK, COLORADO

Samples from hearth, stone ring, or cultural lens features at sites 5SH1912, 5SH3386, 5SH3418, 5SH3439, 5SH3445, 5SH3484, and 5SH3503 were examined for pollen, starch, phytoliths, and/or macrofloral remains. In addition, a mano from 5SH3386 was washed to recover pollen, starches, and phytoliths, while AMS radiocarbon dates were obtained on charcoal from two hearths at 5SH3418. These sites are located in the Great Sand Dunes National Park and Preserve in southern Colorado. Pollen/starch, phytolith, and macrofloral analyses will be used to provide subsistence information concerning plant resources utilized by the various prehistoric occupants of these sites.

研究人员对出土于火塘（hearth）、石圈（stone ring）及文化透镜遗迹（cultural lens features）的遗存样本开展了孢粉、淀粉粒、植硅体（phytoliths）及/或大植物遗存（macrofloral remains）的检测分析，上述样本取自编号为5SH1912、5SH3386、5SH3418、5SH3439、5SH3445、5SH3484及5SH3503的遗址。此外，针对5SH3386遗址出土的手磨（mano），通过冲洗流程回收其表面附着的孢粉、淀粉粒与植硅体；同时对5SH3418遗址两处火塘出土的木炭样本进行了加速器质谱放射性碳定年（AMS radiocarbon dates）测试。上述遗址均坐落于科罗拉多州南部的大沙丘国家公园及保护区（Great Sand Dunes National Park and Preserve）内。本次孢粉/淀粉粒、植硅体及大植物遗存分析工作，旨在揭示上述遗址各史前先民群体所利用的植物资源，进而为复原其生计模式提供科学依据。
