Definition

A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

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

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

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