Formation

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

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.
