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

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

More about Mylonite and Laterite
Here you can know more about Mylonite and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Laterite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Laterite is available in brown, buff, red colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Laterite is Rough and Banded. Properties of rock is another aspect for Mylonite vs Laterite. The hardness of Mylonite is 3-4 and that of Laterite is 2. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Laterite are Not Available.
