What characterizes a batholith?

A batholith is characterized as a large body of igneous rock that forms deep within the Earth's crust. These geological structures are typically formed from the slow crystallization of magma over extended periods. Batholiths can span hundreds of square kilometers and often consist of granite or granodiorite, making them significant components of continental crust.

The size and depth at which batholiths form distinguish them from smaller igneous intrusions, such as stocks or dikes. Their massive scale often results in the formation of mountain ranges once exposed through erosion. Additionally, the presence of a batholith typically indicates past volcanic activity in the region, contributing to the geological history and composition of the area.
