Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Serpentinite vs Mylonite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Serpentinite vs Mylonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Mylonite. Learn more about Serpentinite vs Mylonite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Mylonite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Serpentinite and Mylonite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Mylonite include For road aggregate, Landscaping, Roadstone.
More about Serpentinite and Mylonite
Here you can know more about Serpentinite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Mylonite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Mylonite is available in black to grey colors. Appearance of Serpentinite is Rough and Dull and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Serpentinite vs Mylonite. The hardness of Serpentinite is 3-5 and that of Mylonite is 3-4. The types of Serpentinite are Jadeitite 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 Serpentinite and Mylonite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K 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.Serpentinite is heat resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
