Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1385-3

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，包含两列制表符分隔的数据：1. 拉曼仪角度，2. 计数。样本以0.02度步长的拉曼仪进行测量，使用钴K-α灯泡。文件名由核心标签和样本深度组成，深度以六位数字表示，前导零以下划线分隔，并以_clay.txt结尾。所有原始数据文件存储在一个zip归档中，与该元描述相关联。小于2微米的粘土组分通过阿特贝格法（沉降管）进行定量分离，清洗、干燥并研磨。粘土被重新悬浮并在样品架上进行纹理化处理以供分析。
