Raw data files of X-ray diffraction analysis of the clay fraction from sediment core PS1023-1

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，包含两列由制表符分隔的数据：1. 角度计角度，2. 计数。样本在0.02度的角度计步长下，使用钴K-α灯泡进行测量。文件名由核心标签和样本深度组成，深度以六位数字厘米表示，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，与该元描述相链接。小于2微米的粘土组分通过阿特堡方法（沉降管）进行定量分离，清洗、干燥并磨碎。粘土在样品支架上重新悬浮和纹理化，以便进行分析。
