The X-Ray Laboratory onboard the R/V JOIDES Resolution performs diffraction analyses of minerals and rock powders.
The laboratory uses a Bruker AXS D4 Endeavor XRD. Associated software, EVA, DIFFRACplus and TOPAS, allow for powder diffraction analysis of minerals, including peak-matching and mineral and chemical compound identification. XRD scans from the Bruker can also be analyzed using HighScore (came with Aeris Panalytical XRD) software. The XRD lab provides the scientist scientists with a quick and reliable tool for mineral identification; particularly useful for identifying bulk mineralogy, clays, fine-grained minerals or mixtures of alteration secondary minerals. In addition, XRD can be used to determine mineral proportion.
