Formation

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

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.
