5 Formation

5.1 Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

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.
