We find coesite and stishovite in shocked Coconino Sandstone at meteor Crater. We infer that coesite and stishovite formed from the transformation of quartz at high pressure and temperature. What type phase transformations are these? Explain your answer. (Hint: These high-pressure minerals survive pressure release without transforming back to quartz.)
