IODP Expedition 391 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）可用于识别沉积物或硬岩样品粉末中的矿物种类及其所占比例，实验采用布鲁克AXS D4 Endeavor型X射线衍射仪开展。所得结果以衍射图谱形式返回，支持PDF或PNG两种可查看格式。
