Eruptions, rocks formed by the transportation, deposition, and diagenesis of water flow or glaciers, and sandstone belong to this category; metamorphic rocks are naturally transformed from one stone to another under the mixing of high temperature and high pressure and minerals. , Marble, slate, quartzite, jade are all metamorphic rocks.
