||This animation details the formation of intrusive igneous bodies. Initially, molten magma surges from an underground magma chamber through conduits to breach the surface. As the underground magma cools to solid igneous rock, it creates dikes, sills, and laccoliths. Later erosion uncovers these bodies, including volcanic necks. Further erosion uncovers a batholith.
