Experimental Study on Melting of the Jilin Meteorite and Its Application in Geochemistry

The primitive Material which the Earth consists of is probably IABiron meteorite (core of the Earth) and H-group chondrite (mantle of the Earth). When the experimental temperature is higher than 1300℃, noticeable magmatic differentiation took place in the Jilin chondrite, and this is quite similar to the process of the formation of the core and mantle of the Earth. The metal-sulfide components within chondrite would sink to the core. During melting and recry-stallization of the Jilin chondrite the partial FeOin olivine can be reduced and Fe⁰ formed. These 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 a indicator in identifying the cosmic chondrules.
