IODP Expedition 400 X-ray diffraction (XRD)

X-ray diffraction (XRD) is used to identify minerals and their proportions in sediment or hard rock sample powders on a Bruker AXS D4 Endeavor X-ray diffractometer. Results are returned as diffractograms in a viewable format (either PDF or PNG).X射线衍射（X-ray Diffraction，XRD）技术可借助布鲁克AXS D4 Endeavor型X射线衍射仪，对沉积物或硬岩样品的粉末开展矿物相鉴定及其相对含量分析。测试结果以衍射图谱形式输出，提供可查看的PDF或PNG格式文件。
