Formation

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.

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