The primitive material which the earth consists of is probably IAB iron meteorite (core of the earth) and H-group chondrite (mantle of the earth). When the experimental temperature was higher than 1300 C, noticeable magmatic differentiation took place in the Jilin chondrite, quite similar to the process of formation of the core and mantle of the earth. The metal-sulfide components within chondrite would sink to the core. During melting recrystallization of the Jilin chondrite the partial FeO in olivine can be reduced and Fe(0) formed. This metal Fe also would move to the core. Some large parent meteorite bodies seem to have undergone such a process leading to the formation of some iron meteorites and achondrites. The Fe-Ni-S phase in the experimental products may serve as an indicator in identifying the cosmic chondrules.
