Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1920-2

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：1. 旋转仪角度，2. 计数。样本以0.02度的步长使用钴K-alpha灯泡在旋转仪上测量。文件名由核心标签和样本深度（六位数字厘米，前导零，以下划线分隔）组成，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。通过Atterberg法（沉降管）对小于2微米的粘土成分进行定量分离，清洗、干燥并研磨。粘土在样品支架上重新悬浮并纹理化，以进行分析。
