A large mass of igneous rock that has melted and intruded surrounding strata at great depths.
A massive, frequently discordant, intrusion of coarsely textured plutonic rocks, at least 100 km2 in area and extending 20-30 km down into the layer of magma, which may be composed of several plutons. Granite batholiths, such as Dartmoor, tend to form as domes. Erosion may expose all or part of the upper surface of the batholith.
A well-known batholith is located in the Sierra Nevada range of California.
