1.1 Definition
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

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