A variety of ultrahigh-pressure phases of silicates have been discovered in the vicinity of shocked-induced melt veins in stony meteorites by analytical transmission electron microscopy. The natural ultrahigh-pressure minerals provide us not only the clues to understand the impact events of meteorite parent bodies but also insights into the structure and dynamics of the deep Earth.
