Metamorphic rocks originate from the alteration of the texture and mineral constituents of igneous, sedimentary, and older metamorphic rocks under extreme heat and pressure deep within the earth (seemetamorphism). Some (e.g.,marbleandquartzite) are massive in structure; others, and particularly those...
