Mylonite vs Quartzite 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 Quartzite 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. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite information and Mylonite vs Quartzite characteristics in the upcoming sections.

Mylonite vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Quartzite. Learn more about Mylonite vs Quartzite in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Mylonite and Quartzite, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.

More about Mylonite and Quartzite

Here you can know more about Mylonite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Quartzite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Quartzite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Quartzite is Lustrous. Properties of rock is another aspect for Mylonite vs Quartzite. The hardness of Mylonite is 3-4 and that of Quartzite is 6-7. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Quartzite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Quartzite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
