[OA] Antarctic meteorites / Hayabusa
[OA] 南極隕石 / はやぶさ

Scopes
This session will be held jointly with Hayabusa 2016 (symposium of solar system material), and to present recent research outcomes for Antarctic meteorites and micrometeorites. It will also be an opportunity for general and topical discussion sessions dealing with new data from non-Antarctic meteorites and extraterrestrial materials, and related experimental and theoretical works.
