| Outline of Final Research Achievements |
The deep volatile cycles particularly water is indispensable for understanding the dynamics and chemical evolution of the Earth interior. However the systematic analytical method for volatile in rock samples are not well established in the solid sample, so it was far too far to elucidate its full view. In this study, we established analyses using a secondary ion mass spectrometer (SIMS) for concentration of volatile elements (water, carbon dioxide, fluorine, chlorine, chlorine and sulfur) and isotopic ratios (hydrogen, sulfur) in a least degassed deep submarine volcanic glass and a small melt inclusion incorporated in the magmatic minerals crystallized in deep crustal region. We are applying these analyses to the volcanic glasses at various tectonic setting and we are expecting to bring new development to elucidation of the deep volatile cycles of the Earth interior.
