Synchrotron radiation micro X-ray fluorescence (SµXRF) analysis is a non-destructive method that can be used to identify, and in special cases, to quantify major, minor, and trace elements present in fluid inclusions. In spite of the relevant results, this technique has been used only in a few studies, which, moreover, are mostly focused on either synthetic or natural fluid inclusions in transparent minerals. To investigate fluid inclusions in transparent and opaque minerals, the synchrotron radiation X-ray microprobe station from the µSXRF fluorescence beamline at the LNLS-Campinas was used. This analytical method has been proven to be efficient in the chemical characterization of the fluid inclusions constituents of some transparent (quartz, adularia, emerald, etc.) and opaque minerals (pyrargyrite and hematite).
