Research Abstract

I obtained the following results ; 1) I identified a new mineral from a refractory inclusion, and reconstructed the formation condition. 2) Based on the features of Fe-Ni metal, I discussed the classification and low grade metamorphism of primitive chondrites. 3) From high-pressure minerals and an experimental work, I quantitatively discussed the physical conditions for the parent body collision.
