1.1 Definition

Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas

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

5.1 Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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