| Research Abstract |
Chondrites are imporatant meteorite to clarify the early solarsystem. I obtained the following results; 1)Opaque minerals give constraints on thethermal history of CM chondrites. 2)Minerals in heavily shocked meteorites giveconstraints on the formation conditions. 3)Chondrules formed under various oxygenisotopic reservoirs. 4)The Hayabusa samples derived from LL chondritic body. 5)Theeclogitic xenolith was first discovered from meteorites.
