5.1 Formation

Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
