Formation
Icelandite 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.

Icelandite 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. Icelandite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Icelandite and Properties of Evaporite. Learn more about Icelandite vs Evaporite in the next section. The interior uses of Icelandite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Icelandite and Evaporite, they have various applications in construction industry. The uses of Icelandite in construction industry include Cobblestones, Construction aggregate, 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 Icelandite and Evaporite
Here you can know more about Icelandite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Icelandite and Evaporite consists of mineral content and compound content. The mineral content of Icelandite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon 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 Icelandite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Icelandite is Dull and Soft and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Icelandite vs Evaporite. The hardness of Icelandite is 7 and that of Evaporite is 2-3. The types of Icelandite 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 Icelandite and Evaporite is white. The specific heat capacity of Icelandite is 2.39 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.Icelandite is heat resistant, pressure resistant, scratch resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
