Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Peridotite 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. Peridotite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Evaporite. Learn more about Peridotite vs Evaporite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Peridotite and Evaporite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones 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 Peridotite and Evaporite
Here you can know more about Peridotite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Evaporite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Peridotite is Rough and Shiny and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Peridotite vs Evaporite. The hardness of Peridotite is 5.5-6 and that of Evaporite is 2-3. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite and Evaporite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
