1.1 Definition
Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

5 Formation
5.1 Formation
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
