FTIR reflectance spectral chert database

Hyper-spectral data obtained from 121 chert samples: 60 Ft Payne (30 from Elco, IL; 30 from Florence, AL), 60 Dover (30 from the Brigham Quarry site, TN; 30 from the Thompson Hollow Quarry site, TN), and a single Mookaite chert sample from Australia used as a control. Also included in the spreadsheet are spectral averages of each sample set from a single location. I sheet is 10 spectra taken from a single Dover chert sample and 4 spectra from three color zones in the Mookaite sample. All spectra were obtained using a Bio-Rad FTS-40 FTIR spectrometer in reflectance mode housed at the University of Memphis.本数据集包含121件燧石样品的高光谱（Hyper-spectral）数据：其中60件为Ft Payne型燧石（30件采自伊利诺伊州埃尔科地区，30件采自阿拉巴马州佛罗伦斯地区），60件为多佛燧石（Dover chert）（30件采自田纳西州布里格姆采石场遗址，30件采自田纳西州汤普森霍洛采石场遗址），另有1件采自澳大利亚的穆卡伊特燧石（Mookaite chert）作为对照样品。 电子表格中还收录了各单点位样品组的光谱平均值。 另有一张工作表包含了来自单个多佛燧石样品的10条光谱，以及取自穆卡伊特样品三个颜色区域的4条光谱。 所有光谱均采用安装于孟菲斯大学的Bio-Rad FTS-40型傅里叶变换红外（FTIR）光谱仪以反射模式采集获取。
