Formation

Comendite is a type of Igneous rock which is formed due to cooling and solidification of lava or magma. It may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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