Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

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.
