Question

Quizplus · Accepted Answer

Granitic batholiths are typically associated with subduction zones where magmas are generated through partial melting of the mantle and overlying crust. As the magma rises and cools, it solidifies to form a large plutonic body. These bodies may be uplifted and exposed through erosion, representing the exhumed roots of a subduction-related magmatic arc.
