| Outline of Final Research Achievements |
Multiple-isotope study of primitive meteorites including chondrites and primitive achondrites was undertaken in order to shed light on the origin and evolution of early solar system planetary bodies. To achieve this goal, emphasis was given to technical development leading to high-precision isotope analyses using TIMS and MC-ICP-MS. Meteorites with distinct petrological and geochemical properties were investigated, and important isotope data leading to high-precision chronology of the early solar system objects were obtained.
