Pluton

 

the term used to signify deep-seated igneous bodies. Plutons form when magma from the lower part of the crust or from the mantle cools in the upper layers of the earth’s crust. Their various shapes are determined by the structure of the enclosing rock. Based on dimensions, shape, and bedding in the earth’s crust, the following types of plutons are distinguished: batholiths, laccoliths, lopoliths, phacoliths, dikes, and sills.
