Rock that comes from lava cools very fast and can either be very light and airy or the rocks can be glassy. Igneous Rocks Classification Dark igneous rocks are formed from basaltic or mafic magma. (Mafic because it contains a lot of magnesium and iron). In this sense, igneous rocks are formed when molten rock (magma) solidifies either underneath the earth’s crust to form plutonic (intrusive) igneous rocks or on the surface of the earth to form volcanic (extrusive) igneous rocks. 1.
