Dataset A of article "A machine learning approach for classifying Mediterranean obsidian of archaeometric interest by SEM investigation"

Dataset A used for the manuscript titled "A machine learning approach for classifying Mediterranean obsidian of archaeometric interest by SEM investigation". This dataset is a txt file, tab separated, encoded in UTF-8, with newline line terminator. A compressed zip file is also provided, which, expanded, will create a directory containing 890 files. The files come in couples with the same name and two different extensions: spc (with SEM-EDS spectroscopy data) and tif (with SEM-BSE images). The SEM-EDS data refers to the same sample area shown in the SEM-BSE image going under the same name.本数据集A用于题为《基于扫描电子显微镜（Scanning Electron Microscope, SEM）分析开展考古学相关地中海黑曜石分类的机器学习方法》的学术手稿。该数据集为制表符分隔的纯文本（.txt）文件，采用UTF-8编码，以换行符作为行终止符。另附有一个压缩ZIP文件，解压后将生成包含890个文件的目录。该目录下的文件以同名成对形式存在，拥有两种不同扩展名：.spc（包含扫描电子显微镜-能谱仪（Scanning Electron Microscope-Energy Dispersive X-ray Spectroscopy, SEM-EDS）光谱数据）与.tif（包含扫描电子显微镜-背散射电子（Backscattered Electron, BSE）图像）。同名的SEM-EDS数据与SEM-BSE图像对应同一采样区域。
