| Outline of Final Research Achievements |
The purpose of this study was to understand the formation conditions of planetary materials in the solar nebula and secondary alteration processes on the parent asteroids.
We have conducted the mineralogical and spectroscopic studies on primitive carbonaceous chondrites CV, CO and CR chondrites. Our systematic studies on CV chondrites shows the local heterogeneity of the degree of aqueous alteration and thermal metamorphism on CV chondrite parent body. In addition, we have applied the similar approach to the Hayabusa samples and Wild 2 comet particles and compared them to the mineralogy of primitive chondrites.
