Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Evaporite vs Arkose 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 Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Arkose. Learn more about Evaporite vs Arkose in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Arkose, 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 Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Evaporite and Arkose
Here you can know more about Evaporite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Arkose consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Arkose, 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, Arkose is available in reddish brown colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Arkose is Rough and Dull. Properties of rock is another aspect for Evaporite vs Arkose. The hardness of Evaporite is 2-3 and that of Arkose is 6-7. The types of Evaporite are Sedimentary rock whereas types of Arkose are Arkose. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Arkose is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Arkose is 0.78 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 Arkose is heat resistant, impact resistant, pressure resistant.
