Classification diagram for igneous rocks. Igneous rocks are classified according to the relative abundances of different minerals. A given rock is represented by a vertical line in the diagram. In the ultramafic field, the arrows represent a rock containing 40% olivine and 60% pyroxene. The name an igneous rock gets depends not only on composition, but on whether it is intrusive or extrusive
