Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1382-1

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.文件格式为纯文本，包含两列以制表符分隔的数据：第一列为测角仪角度（Angle of goniometer），第二列为计数（Counts）。样品采用钴Kα射线管（Cobalt K-alpha bulb）进行测试，测角仪步长设置为0.02°。文件名由岩心标识与以六位带前导零的数字表示的样品深度（单位：厘米）组成，各部分以下划线分隔，最终以_clay.txt作为文件名后缀。所有原始数据文件均存储于一个ZIP压缩归档中，与本元数据描述相关联。粒径小于2微米的黏土组分通过阿特贝格法（Atterberg method，沉降管法）完成定量分离，随后经洗涤、干燥与研磨处理。将制备好的黏土重新悬浮后，均匀铺展于样品架上以供分析测试。
