[P-PS12] Formation and evolution of planetary materials in the solar system

Tue. May 24, 2016 10:45 AM - 12:15 PM 104 (1F)

Convener:*Masaaki Miyahara(Department of Earth and Planetary Systems Science, Graduate School of Science, Hiroshima University), Akira Yamaguchi(National Institute of Polar Research), Tomohiro Usui(Department of Earth and Planetary Sciences,Tokyo Institute of Technology), Yoko Kebukawa(Faculty of Engineering, Yokohama National University), Wataru Fujiya(Ibaraki University, College of Science), Yusuke Seto(Graduate School of Science, Kobe University), Shoichi Itoh(Graduate school of Science, Kyoto University), Chair:Tomohiro Usui(Department of Earth and Planetary Sciences,Tokyo Institute of Technology)

This session will focus on understanding the evolution in the solar system with interaction and co-evolution in minerals, water, organic matter and noble gas in chondritic meteorites and interplanetary dust. New innovative analytical and theoretical techniques in various fields will be discussed. The developing methods are welcome to submit for the future mainstream of meteorite study.
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 research works on differentiated meteorites and parent body processes for chondrites such as shock metamorphism, thermal metamorphism, alteration and volcanic activity are especially included in this session.
Presentation materials in English are highly recommended for all participants in this session.
