5.1 Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
