IODP Expedition 346 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）技术依托布鲁克AXS D4 Endeavor型X射线衍射仪，对沉积物或硬岩样品粉末中的矿物种类及其占比进行鉴定。所得结果将以可查看格式（涵盖PDF与PNG两种格式）的衍射图谱形式返回。
