Outline of Final Research Achievements

Meteorites contain aqueous altered minerals having information of parent body water. Because metal in primitive meteorites contains no oxygen species originally, comparison between oxidized metal in meteorite and experimental products is useful to understand the oxidation in the early solar system. In this study, oxygen isotope imaging for aqueous laterd minerals was performed using automated isotope microscope system and developed an oxygen isotope experimental instrument using a sorption pump.
