  • Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), Making of proto-planets by melting of chondrite at high-pressure, GREAUX STEEVE, STAGNO VINCENZO, TATENO SHIGEHIKO, We investigated the melting temperatures and phase relations of chondrite materials at high-pressure. The objective of this study is to understand early planetary differentiation processes such as core formation, mantle bulk composition and redox state of primordial mantle in early terrestrial planets. Melting experiments were carried out on natural carbonaceous (origin: Tagish Lake) and enstatite (origin: Sahara) chondrites at high pressure and temperatures using the multi-anvil apparatus. Our results show the effect of volatile on the melting temperature of Tagish Lake (CI2) and Sahara (EH3) with respect to Allende (CV3) meteorite and KLB1, respectively. We established the phase equilibria which can be used to derive a model of accretion and possible core segregation that takes into consideration the stability of carbon and hydrous species along with a Fe-Ni sulfide melt. This result leads to important implications for the evolution of the primordial mantle of terrestrial planets.
  • Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (S), Chemical composition of the lower mantle and differentiation of the early Earth, IRIFUNE Tetsuo, Experimental techniques for sound velocity measurements and high pressure and temperature generation using Kawai-type multi-anvil apparatus have been expanded to the deeper regions of the Earth’s lower mantle. A number of new experimental results particularly relevant to the following topics have been obtained under the pressure and temperature conditions of the deep lower mantle; 1) ultrasonic sound velocity measurements on major high-pressure minerals in the mantle and subducting slabs, 2) melting temperatures, melting relations, and element partitioning among high pressure minerals of the lower mantle materials, 3) phase relations and stabilities of some major mantle minerals and hydrous minerals, leading to important implications for the chemical compositions, evolution, and dynamics of the lower mantle of the Earth.
