[P-PS10]Formation and evolution of planetary materials in the Solar System
convener:Wataru Fujiya(Ibaraki University, College of Science), Megumi Matsumoto(Graduate School of Science, Tohoku University), Shin Ozawa(Department of Earth Science, Graduate School of Science, Tohoku University), Yuki Hibiya(Submarine Resources Research Center, Japan Agency for Marine-Earth Science and Technology)
In this session, we will discuss the material evolution in the Solar System based on extraterrestrial sample analyses and experimental works. We will look over recent knowledge from primitive materials such as chondrites, interplanetary dust particles, and returned samples by space missions. 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 are highly welcome to submit for future studies of the Solar System evolution.
