Metamorphic rock

What are metamorphic rocks. What are they made of. How they look like. How are they formed. Learn their types with characteristics, examples, pictures, & fun facts.

The major types of metamorphic rocks are detailed here, which include regional, contact and mechanical metamorphism.

Learn about the metamorphic rock called hornfels, including how it gets it name, its composition, characteristics, sources, and uses.

Schist is medium grade metamorphic rock, formed by means of the metamorphosis of mudstone / shale, or some forms of igneous rock, to a higher than slate

Metamorphic rocks are formed by great heat and pressure. Most of the thousands of rare minerals known to science occur in these rocks. Learn more.

Metamorphic rocks are most often found in mountainous regions though they can be seen wherever there are signs of geological upheaval in an area. This type of rock is formed by the transformation of another rock type, a change that is usually triggered by tremendous heat, pressure or other violent phenomena. The forces that cause metamorphic rocks to form are so great that they change not only the appearance but also the chemical composition of an existing rock.

How are metamorphic rocks formed? Metamorphic rocks are created from exposure to extreme heat and pressure, becoming a whole new rock.
