Formation
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Foidolite 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. Foidolite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Foidolite and Properties of Evaporite. Learn more about Foidolite vs Evaporite in the next section. The interior uses of Foidolite 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 Foidolite and Evaporite, they have various applications in construction industry. The uses of Foidolite in construction industry include As dimension stone, Cement manufacture, For road aggregate 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 Foidolite and Evaporite
Here you can know more about Foidolite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Foidolite and Evaporite consists of mineral content and compound content. The mineral content of Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all . When we have to compare Foidolite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Foidolite is available in black, brown, colourless, green, grey, pink, white colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Foidolite is Dull and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Foidolite vs Evaporite. The hardness of Foidolite is 1.5 and that of Evaporite is 2-3. The types of Foidolite 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 Foidolite and Evaporite is white. The specific heat capacity of Foidolite 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.Foidolite is heat resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
