Contact metamorphism is a rock-forming process which occurs when hot magma forces its way into rock.
Further Explanation
Rocks are aggregates of minerals and majorly of three types:
- Igneous Rocks
- Sedimentary Rocks
- Metamorphic Rocks
Igneous rocks are created when lava cools down and solidify in rock. The metamorphic rocks are made by the subjection of igneous rocks and sedimentary rocks under high pressure and temperature. The sedimentary rocks are created by continuous deposition of minerals, earlier rocks, and animal.
When magma gets in contact with a rock such as sedimentary rock, it changes its mineralization and texture due to heat. Sedimentary rock will change to slate, limestone to marble. The other type of metamorphism is regional metamorphisms and occurs in rocks over a wide area, deep in the earth's crust, due to immense pressure and temperature.
Some example of igneous rocks is granite and made up of a mixture of element and . Examples of sedimentary rocks are breccias and siltstone. Example of metamorphic rocks is marble.
