Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
  
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.
