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.

Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
