Definition

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

Formation

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

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
