Research Abstract

Our study by using electron microscopy and synchrotron radiation X-ray diffraction revealed detailed mineralogical characteristics of shock melts in some primitive meteorites shocked at high temperatures. Our shock experiments of a primitive meteorite showed that shock heating effects at high temperatures were very different from those at a room temperature. We also found chondrules surrounded by rims in some primitive meteorites resulted from shock-induced brecciation and proposed a new parent-body formation model of the meteorite textures.
