The most common plutonic igneous rock is granite. There are various types of granite based on whether the rock cooled above or below the surface of the earth. The major differences among these types of granitic rock is their crystalline structure.
Exfoliation of bodies of granite rock can occur from chemical weathering of the surface, differences in temperature, salt crystallization, and release of pressure.

Exfoliation.
When a mass of rock is exposed by weathering and by removal of the overlying rock there is a decrease in the confining pressure on the rock, and a slight expansion of the rock volume. This unloading promotes cracking of the rock – known as exfoliation - and the development of cracks leads to other kinds of weathering.
