Mylonite vs Evaporite 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 Evaporite 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 water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. 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 Evaporite information and Mylonite vs Evaporite characteristics in the upcoming sections.

More about Mylonite and Evaporite

Here you can know more about Mylonite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Evaporite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Evaporite is available in green, grey, silver, white colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Mylonite vs Evaporite. The hardness of Mylonite is 3-4 and that of Evaporite is 2-3. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Evaporite are Sedimentary rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Evaporite is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Evaporite is 0.92 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 Evaporite is heat resistant, pressure resistant.
