Scoria 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. Scoria vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Evaporite. Learn more about Scoria vs Evaporite in the next section. The interior uses of Scoria 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 Scoria and Evaporite, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works 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 Scoria and Evaporite
Here you can know more about Scoria and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Evaporite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Scoria vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Scoria is Glassy and Vesicular and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Scoria vs Evaporite. The hardness of Scoria is 5-6 and that of Evaporite is 2-3. The types of Scoria are Not Available whereas types of Evaporite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Scoria and Evaporite is white. The specific heat capacity of Scoria is Not Available 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
