WebMetamorphism often involves fluids that promote chemical reaction. Most metamorphic fluids are H 2 O-rich. Major kinds of metamorphism include burial metamorphism, regional metamorphism, contact metamorphism, dynamic metamorphism, hydrothermal metamorphism, and impact metamorphism. WebShock Metamorphism. When extraterrestrial objects hit Earth, the result is a shock wave. Where the object hits, pressures and temperatures become very high in a fraction of a second. A “gentle” impact can hit with 40 GPa and raise temperatures up to 500 °C.
