Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism
From Greek mulōn mill + -ite

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