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