スコープ和文Impact phenomena have been recognized to play essential roles in the processes of planetary evolution. Recent progresses in nanoscale analysis of meteorites, asteroid explorations, as well as laboratory experiments for simulating shock dynamics on planetary materials are collaboratively revealing complex effects of shock-induced processes in planetary evolution. Recently, several new metastable high-pressure phases have been identified in strongly shocked meteorites. Their occurrences indicate that the shock-induced physical states are far from thermodynamic equilibrium and contain very complicated processes. On the other hand, laboratory experiments including laser-driven shock techniques have recently been making remarkable progresses. They successfully simulate a variety of fast non-equilibrium processes at transient high-pressure conditions reaching tens to a few hundreds of gigapascals, that uniquely affect the physical and chemical properties of planetary materials upon impacts. Here we discuss how planetary materials are compressed, fractured, transformed, melted, and quenched during impact events by referring these recent studies. We welcome presentations from interdisciplinary research fields related to shock responses of planetary materials.
