Answer
A batholith is a large, intrusive igneous rock body formed from solidified magma that has intruded into the Earth's crust and cooled slowly at depth. Batholiths are typically composed of granitic or other coarse-grained rocks. They are generated in modern tectonic settings where the Earth's crust is undergoing crustal thickening and mountain-building processes, often in association with convergent plate boundaries. For example, many batholiths are found in regions associated with continental collision, subduction zones, or continental rifting.
