Formation of Metamorphic Rocks Metamorphic rocks are formed from any type of rock that changes as a result of intense heat and pressure in the Earth’s crust. For example, as sedimentary shale is exposed to more heat and pressure, it changes into different types of metamorphic rocks. slate schist gneiss schist phyllite gneiss shale P H contact metamorphosis magma sedimentary rock contact metamorphosis regional metamorphosis contact metamorphosis magma sedimentary rock contact metamorphosis regional metamorphosis Contact metamorphism occurs when rocks come in contact with magma. Regional metamorphism occurs when intense pressure, such as mountain formation, changes large-scale areas of rocks. Classifying Metamorphic Rocks Metamorphic rocks are classified as foliated or nonfoliated. The texture of nonfoliated metamorphic rocks is not arranged in bands. Examples include marble, that is formed from limestone, and quartzite, that begins as sandstone. Foliated metamorphic rock - arranged in layers foliated metamorphic rock slate gneiss bands marble quartzite limestone sandstone Heat & Pressure Foliated rocks, like slate and gneiss, have grains arranged in thin parallel layers or bands.
