Definition

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

Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of basalt

Formation

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

Pyrolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
