POLLEN AND ORGANIC RESIDUE (FTIR) ANALYSES AT EIGHT SITES FOR THE ANADARKO HOWELL SALT CREEK CO2 PIPELINE PROJECT, WYOMING

Eight archaeological sites along the Anadarko Howell Salt Creek CO2 Pipeline project
were sampled for pollen to identify paleoenvironmental conditions along this transect in central
Wyoming. In addition, pollen analysis of housepit floors and ground stone addresses questions
of subsistence. Use of the Fourier Transform Infrared Spectrometer (FTIR) assists in
identifying subsistence patterns at these sites through identification of organic residue from
samples representing hearths, housepit floors, activity areas, and ground stone. Each of the
eight sites will be discussed individually before drawing conclusions and integrating the
information concerning the paleoenvironment and subsistence from these eight sites.

针对阿纳达科·豪厄尔盐溪二氧化碳（CO₂）管道项目沿线的8处考古遗址开展孢粉采样，以探明怀俄明州中部该样带沿线的古环境状况。此外，通过对房址坑堆积面与磨制石器开展孢粉分析，可解答生计模式相关问题。傅里叶变换红外光谱仪（Fourier Transform Infrared Spectrometer, FTIR）的应用，可通过识别灶址、房址坑堆积面、活动区以及磨制石器样本中的有机残留物，辅助厘清上述遗址的生计模式。本次研究将先逐一介绍这8处遗址，随后综合整合这8处遗址的古环境与生计相关信息并得出最终结论。
