Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1369-1

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.文件格式为文本文件，包含两列以制表符分隔的数据：1. 测角仪（goniometer）角度，2. 计数结果。样品采用钴Kα射线源（Cobalt K-alpha bulb）进行测量，测角仪步长为0.02°。文件名由核心标签、带前导零的六位厘米级样品深度值通过下划线连接构成，后缀为_clay.txt。所有原始数据文件均存储于一个ZIP压缩归档文件中，与本次元描述相关联。粒径小于2微米的粘土组分通过阿特贝格法（Atterberg method，沉降管法）定量分离，随后经洗涤、干燥与研磨处理。将所得粘土重新悬浮后，均匀铺展于样品架上制样以供分析。
