Introduction of Research
Meteorites are known to be mainly originated from asteroids. Especially, chondrite meteorites derived from undifferentiated bodies directly preserve solar protoplanetary dusts and record early events of our Solar System. I investigate in-situ measurements of isotopic compositions of chondritic components to reconstruct conditions and processes in the early Solar System.
