Scopes
This session is to present recent research outcomes for Antarctic meteorites. It will also be an opportunity for general and topical discussion sessions dealing with new data from non-Antarctic meteorites and planetary research.

Convener: Akira Yamaguchi (NIPR)

セッションの趣旨
本セッションは、南極隕石からの最新の成果について議論されます。また、非南極隕石や惑星科学について議論されます。

コンビーナ：山口 亮（国立極地研究所）
