Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

Evaporite vs Dacite 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 Dacite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Dacite. Learn more about Evaporite vs Dacite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Dacite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Evaporite and Dacite, 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 Dacite include As dimension stone, Construction aggregate, For road aggregate, Landscaping.
More about Evaporite and Dacite
Here you can know more about Evaporite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Dacite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Dacite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in colourless, green, grey, silver, white colors whereas, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Dacite is Vesicular. Properties of rock is another aspect for Evaporite vs Dacite. The hardness of Evaporite is 2-3 and that of Dacite is 2-2.25. The types of Evaporite are Not Available whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Dacite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Dacite 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.Evaporite is heat resistant, pressure resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
