| Outline of Final Research Achievements |
Fluid inclusions in minerals represent host fluid when the mineral has been grown in planet interior and in the past. The fluid consists of hydrogen, oxygen, carbon and nitrogen and their isotopic compositions are useful to study origin of the fluid. In this study, we developed a novel analytical method for isotopic analysis of fluid inclusions applying secondary ion mass spectrometry with cryogenic freezing of samples. We also developed grinding and polishing techniques to expose fluid inclusions on the sample surface under cryogenic conditions.
