Pictures of Metamorphic Rocks

By

Metamorphic rocks are those that form by the effects of heat, pressure and shear upon igneous and sedimentary rocks. Some form during mountain-building by forces of regional metamorphism, others from the heat of igneous intrusions in contact metamorphism. A third category forms by the mechanical forces of fault movements: cataclasis and mylonitization.

This is just a starting point to explore the variety in metamorphic rocks.
