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）技术可用于鉴定沉积物或硬岩样品粉末中的矿物种类及其占比，测试依托布鲁克AXS D4 Endeavor型X射线衍射仪完成。所得结果将以可查看的衍射图谱形式输出，格式支持PDF或PNG。
