Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1394-4@en

Format of files is text, two tab-delimited columns: 1. Angle of goniometer, 2. Counts. Samples were measured with a Cobalt K-alpha bulb in goniometer steps of 0.02 degree. File names consist of core label and depth of sample in six digits cm with leading zeros separated by an underline and ending with _clay.txt. All raw data files are stored in one zip-archive, linked to this metadescription. Clay fraction less than 2 micron was quantitatively separated by Atterberg method (settling tube), washed, dried and milled. Clay was resuspended and texturized on sample holder for analysis.文件格式为纯文本，包含两列以制表符分隔的数据：第一列为测角仪（goniometer）角度，第二列为计数数值。测试样品采用钴Kα辐射源（Cobalt K-alpha bulb）进行表征，测角仪扫描步长设置为0.02度。文件名由核心标签、带前导零的6位厘米级样品深度值通过下划线连接而成，后缀为_clay.txt。所有原始数据文件均存储于一个压缩归档文件中，并与本元描述关联。粒径小于2微米的黏土组分通过阿特伯格法（Atterberg method，沉降管法）完成定量分离，随后经洗涤、干燥与研磨处理。将所得黏土重新悬浮后，涂覆于样品支架上制备分析试样。
