[P-PS08] Formation and evolution of planetary materials in the Solar System

Sun. May 26, 2024 10:45 AM - 12:15 PM 104 (International Conference Hall, Makuhari Messe)

convener:Noriyuki Kawasaki(Department of Earth and Planetary Sciences, Graduate School of Science, Hokkaido University), Toru Matsumoto(The Hakubi Center for Advanced Research, Kyoto University), Minako Hashiguchi(Nagoya University), Atsushi Takenouchi(Kyoto University), Chairperson:Minako Hashiguchi(Nagoya University), Noriyuki Kawasaki(Department of Earth and Planetary Sciences, Graduate School of Science, Hokkaido University)

In this session, we will discuss the material evolution in the Solar System based on extraterrestrial sample analyses and experimental works. We will overlook recent knowledge from primitive materials such as chondrites, interplanetary dust particles, and returned samples by space missions (ex. Hayabusa 2 mission). Research works on meteorite parent body processes such as aqueous alteration, thermal metamorphism, shock metamorphism, volcanic activity, and core-mantle-crust differentiation will also be discussed. The topics of this session include experimental studies which, together with meteorite studies, help us to understand the material formation/evolution in the Solar System as well as processes on meteorite parent bodies. Presentations on new innovative analytical and theoretical techniques in various research fields (chemistry, theoretical calculation, physical property), and exploratory research by students are highly welcome to improve future studies of the Solar System evolution. This session is J (Japanese) session but English talks are also welcomed.
