The set of high temperature- pressure minerals in the shocked meteorites of Shahdad
Keywords:
High pressure polymorphs, Melt veins, Chondrite type H4, MeteoritesAbstract
In this study, 3 pieces of meteorites KM97003, KM97007, KM97008 of chondrite type H4, which are strongly shocked and contain high pressure polymorphs of main minerals (olivine, pyroxene, feldspar and quartz), in order to investigate high temperature-pressure minerals which is created during the sudden transformations caused by the shock to the meteorite, has been studied. The size of these high-pressure minerals is micron to less than micron and they are inside or in the vicinity of shock-induced melt veins and melt cavities in chondrite. The purpose of this article is to review and summarize the findings related to high pressure natural minerals in Shahdad shocked meteorites.
