Mylonite is one of the important type of rocks. If we have to define Mylonite in general, Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. Mylonite comes under Metamorphic Rocks. All Metamorphic Rocks have similar properties and formation process.
