1.1 Definition
Breccia is a rock consisting of angular fragments of stones which are cemented by finer calcareous material
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

5 Formation
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.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
