Preliminary study on the chemical mapping of individual fluid inclusion bysynchrotron X-ray fluorescence microprobe

Synchrotron X-ray fluorescence analyses on individual hypersaline fluid inc lusions were tested using synchrotron source at Tsukuba (KEK), Japan. The X RF instrumentation at KEK meets the purpose of fluid inclusion analysis, no n-destructive, multi-element, ppm detection limits, with micro spatial reso lution. In practice, however, the quantitative chemical analysis of fluid i nclusion requires further considerable data accumulation. Semi-quantitative distribution of elements (mass number >25) in single fluid inclusion was o btained.
