The largest of all igneous intrusions is called a batholith. Batholiths are formed by the massive invasion of hot magma into country rock.
The general term for igneous intrusions is "plutons". Plutons are bodies of intrusive igneous rock that form underground through the solidification of magma.

Faults, intrusions, and extrusions are all geologic features related to the movement of the Earth's crust. Faults are fractures along which rocks have moved, intrusions are igneous rocks that have been forced into pre-existing rocks, and extrusions are igneous rocks that have been extruded onto the Earth's surface. They all involve the movement and displacement of rocks, contributing to the shaping of the Earth's crust.
Igneous intrusions injected between horizontal layers are known as sills. Sills are tabular intrusions that are typically parallel to the layering of the existing rock formations. They are formed when magma is injected horizontally into existing rock layers and solidifies underground.
Intrusions of igneous rock are typically younger than the rock layers they penetrate. This is because the magma that forms igneous intrusions is usually injected after the surrounding rocks have already solidified and formed.

Igneous rocks can be changed to sedimentary rocks outside of igneous intrusions. This is due to silt built up and weathering.

Igneous intrusions form when magma cools and solidifies before it reaches the surface. Three common types of intrusion are sills, dykes, and batholiths
These are known as sills.

Names given to different types of igneous intrusions are attributed to their shapes and sizes, as well as how they form within the Earth's crust. Common types include dikes, sills, laccoliths, and batholiths, each with unique characteristics based on their formation processes.
Igneous intrusions injected between horizontal layers are known as sills. Sills are tabular intrusions that are typically parallel to the layering of the existing rock formations. They are formed when magma is injected horizontally into existing rock layers and solidifies underground.
The main types of igneous intrusions are dikes (vertical tabular bodies), sills (horizontal tabular bodies), laccoliths (intrusions causing overlying strata to arch up), and batholiths (large, dome-shaped intrusive formations).
Intrusions of igneous rock are typically younger than the rock layers they penetrate. This is because the magma that forms igneous intrusions is usually injected after the surrounding rocks have already solidified and formed.
The four main intrusive igneous features are dikes (tabular intrusions that cut across rock layers), sills (tabular intrusions that run parallel to rock layers), laccoliths (mushroom-shaped intrusions with a flat base), and batholiths (large, dome-shaped intrusions that form the core of mountain ranges).
