Enderbite and Mylonite


Definition

Definition
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

Formation

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.   
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
