Metamorphites
The metamorphic rocks are derived from pre-existing sedimentary and magmatic rocks by mineralogical, chemical, and structural changes, essentially in the solid state, in response to marked changes in temperature and/or pressure (both hydrostatic and oriented), during deeper burial into deeper parts of the Earth´s crust. During these processes parallel orientation of newly formed minerals generally forms (schistosity). Hydrothermal metamorphism represents a special type, because it is related to the migration of solutions near ore veins. Contact metamorphism results from temperature effect near contact with magmatite bodies.
