Abstract

Some meteorites experienced transient high-pressure and -temperature conditions on its parent -body. High-pressure polymorphs form in and around shock-melt veins of shocked meteorites. Recent developed Nano-technologies such as TEM and FIB system allow us to scrutinize high-pressure polymorphs in shocked meteorites. We here introduce the occurrences, natures and formation mechanisms of high-pressure polymorph of olivine and silica in shocked meteorites and their implications for planetary science.
