5.1 Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
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.
