Formation

Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

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

Evaporite vs Mylonite 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 Evaporite and Mylonite Reserves. A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. 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 Evaporite vs Mylonite information and Evaporite vs Mylonite characteristics in the upcoming sections.

More about Evaporite and Mylonite

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