Igneous petrology is the study of igneous rocks, which are formed through the solidification of molten material (magma or lava). Igneous rocks are classified based on their mode of formation (intrusive or extrusive) and their mineral composition. Intrusive igneous rocks form when magma cools and solidifies beneath the Earth's surface.
