Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Anorthosite is a phaneritic, intrusive igneous rock which is characterized by a predominance of plagioclase feldspar which is almost 90–100%, and a minimal mafic component.

Evaporite vs Anorthosite 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 Anorthosite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Anorthosite. Learn more about Evaporite vs Anorthosite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Anorthosite include Decorative aggregates, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Anorthosite, 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 Anorthosite include As dimension stone, Cement manufacture, For road aggregate.
More about Evaporite and Anorthosite
Here you can know more about Evaporite and Anorthosite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Anorthosite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Anorthosite includes Amphibole, Clinopyroxene, Ilmenite, Magnetite, Olivine, Orthopyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Anorthosite, 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, Anorthosite is available in black, bluish - grey, brown, green, grey, light greenish grey, pink, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Anorthosite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Evaporite vs Anorthosite. The hardness of Evaporite is 2-3 and that of Anorthosite is 5-6. The types of Evaporite are Sedimentary rock whereas types of Anorthosite are Proterozoic Anorthosite and Archean Anorthosite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Anorthosite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Anorthosite is 0.84 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 Anorthosite is heat resistant, impact resistant, pressure resistant, scratch resistant, wear resistant.
