The original rock may be a sedimentary rock, an igneous rock or another older metamorphic rock. Igneous rocks: began as magma (molten rock) which cooled and crystallized into minerals. This magma can be derived …
WebFour common types of foliated metamorphic rocks, listed in order of metamorphic grade or intensity of metamorphism are slate, phyllite, schist (pronounced “shist”), and gneiss (pronounced “nice”).
