Dunite 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 Dunite and Evaporite Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. 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 Dunite vs Evaporite information and Dunite vs Evaporite characteristics in the upcoming sections.

Dunite vs Evaporite 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. Dunite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Evaporite. Learn more about Dunite vs Evaporite in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Dunite and Evaporite, they have various applications in construction industry. The uses of Dunite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Evaporite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Dunite and Evaporite

Here you can know more about Dunite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Evaporite consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Evaporite is available in green, grey, silver, white colors. Appearance of Dunite is Rough and Shiny and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Dunite vs Evaporite. The hardness of Dunite is 3.5-4 and that of Evaporite is 2-3. The types of Dunite are Dunite 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 Dunite and Evaporite is white. The specific heat capacity of Dunite is 1.25 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.Dunite is heat resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
