5.1 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.
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.
