batholith | geology | Britannica

batholith, large body of igneous rock formed beneath the Earth’s surface by the intrusion and solidification of magma. It is commonly composed of coarse-grained rocks (e.g., granite or granodiorite) with a surface exposure of 100 square km (40 square miles) or larger. A batholith has an irregular shape with side walls that incline steeply against the host rock. Most batholiths intrude across …
