Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1466-1

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，包含两列以制表符分隔的数据：1. 旋转台角度，2. 计数。样品以0.02度的旋转台步长，使用钴K-α灯泡进行测量。文件名由核心标签和样品深度（六位数字，以零开头，由下划线分隔）组成，并以_clay.txt结尾。所有原始数据文件存储在一个zip存档中，并与本元数据描述相关联。小于2微米的粘土组分通过Atterberg方法（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载体上进行纹理化处理以进行分析。
