Fig. 1From: Effect of grain size on amorphization mechanism and kinetics of bridgmanite in shocked meteoritesSecondary electron images of bridgmanite before and after amorphization. a Synthesized polycrystalline bridgmanite used as starting material. b Partially amorphized bridgmanite after high-temperature annealing at 554 K (FBRD09). The darker regions surrounding the bridgmanite grains represent amorphous phasesBack to article page
