Formation

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.   
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Mylonite vs Peridotite 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 Peridotite 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. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite information and Mylonite vs Peridotite characteristics in the upcoming sections.

Mylonite vs Peridotite 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. Mylonite vs Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Peridotite. Learn more about Mylonite vs Peridotite in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Mylonite and Peridotite, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Peridotite include As dimension stone, Cobblestones.

More about Mylonite and Peridotite

Here you can know more about Mylonite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Peridotite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Peridotite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Peridotite is available in dark greenish - grey colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Mylonite vs Peridotite. The hardness of Mylonite is 3-4 and that of Peridotite is 5.5-6. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Peridotite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
