Definition
Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution

Etymology
From Auvergne region of France used by a French geologist Alexandre Brongniart in 1826 who applied this term to some feldspathic sandstones
From a sediment left after the evaporation

Formation
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 is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Arkose 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. Arkose vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Arkose and Properties of Evaporite. Learn more about Arkose vs Evaporite in the next section. The interior uses of Arkose include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Arkose and Evaporite, they have various applications in construction industry. The uses of Arkose in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, 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 Arkose and Evaporite
Here you can know more about Arkose and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Arkose and Evaporite consists of mineral content and compound content. The mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Sedimentary Rocks. When we have to compare Arkose vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Arkose is available in reddish brown colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Arkose is Rough and Dull and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Arkose vs Evaporite. The hardness of Arkose is 6-7 and that of Evaporite is 2-3. The types of Arkose 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 Arkose and Evaporite is white. The specific heat capacity of Arkose 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.Arkose is heat resistant, impact resistant, pressure resistant whereas Evaporite is heat resistant, pressure resistant.
