[P-PS22_1AM1] Planetary processes from meteorites and experimental works

Thu. May 1, 2014 9:00 AM - 10:45 AM 415 (4F)

Convener:*Makoto Kimura(Faculty of Science, Ibaraki University), Eiji Ohtani(Department of Earth and Planetary Materials Science, Graduate School of Science, Tohoku University), Masaaki Miyahara(Department of Earth and Planetary Systems Science, Graduate School of Science, Hiroshima University), Chair:Masaaki Miyahara(Department of Earth and Planetary Systems Science, Graduate School of Science, Hiroshima University)

In order to explore the planetary materials and their evolution, both meteorites and experimental studies are necessary. In this session, we will discuss these topics from meteorites and experimental works. The reserach works on differentiated meteorites and parent body processes for chondrites are especially included in this session.
