1.1 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

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'.

5.1 Formation

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

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.

Mylonite vs Serpentinite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Mylonite and Serpentinite Reserves. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. 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'.. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Mylonite vs Serpentinite information and Mylonite vs Serpentinite characteristics in the upcoming sections.

More about Mylonite and Serpentinite

Here you can know more about Mylonite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Serpentinite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Mylonite vs Serpentinite. The hardness of Mylonite is 3-4 and that of Serpentinite is 3-5. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mylonite is heat resistant, impact resistant, pressure resistant whereas Serpentinite is heat resistant.
