Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Evaporite vs Granulite 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. Evaporite vs Granulite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Granulite. Learn more about Evaporite vs Granulite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Granulite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Hotels, Interior decoration, Kitchens and Stair treads. Due to some exceptional properties of Evaporite and Granulite, they have various applications in construction industry. The uses of Evaporite in construction industry 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 and that of Granulite include As dimension stone, Building houses or walls.
More about Evaporite and Granulite
Here you can know more about Evaporite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Granulite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Granulite, 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, Granulite is available in black, brown colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Evaporite vs Granulite. The hardness of Evaporite is 2-3 and that of Granulite is 6-7. The types of Evaporite are Sedimentary rock whereas types of Granulite are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Granulite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
