Formation

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

Harzburgite 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.
