Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Breccia is a clastic sedimentary rock which is composed of broken fragments of minerals or rock which are cemented together by a fine-grained matrix and it forms where broken, angular fragments of rock or mineral debris accumulate.
