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

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.

More about Laterite and Mylonite
Here you can know more about Laterite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Mylonite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Mylonite is available in black to grey colors. Appearance of Laterite is Rough and Banded and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Laterite vs Mylonite. The hardness of Laterite is 2 and that of Mylonite is 3-4. The types of Laterite are Not Available whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Laterite and Mylonite is white. The specific heat capacity of Laterite is Not Available and that of Mylonite is 1.50 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Laterite is heat resistant, pressure resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
