Metamorphic Rocks. Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting.If melting occurs, magma is formed, starting the rock cycle all over again. the temperature and pressure conditions (metamorphic environment) in which the rock was formed. 2  the composition of the parent, or original unmetamorphosed, rock. 3  aids in the interpretation of the platetectonic setting in which the metamorphism took place. 4  aids in the reconstruction of the geological history of an area.
