Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Ijolite 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 vs Ijolite 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 Ijolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Ijolite. Learn more about Evaporite vs Ijolite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Ijolite include Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Evaporite and Ijolite, 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 Ijolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Evaporite and Ijolite
Here you can know more about Evaporite and Ijolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Ijolite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Ijolite, the texture, color and appearance plays an important role in determining the type of rock. Evaporite is available in green, grey, silver, white colors whereas, Ijolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Ijolite is Banded and Foilated. Properties of rock is another aspect for Evaporite vs Ijolite. The hardness of Evaporite is 2-3 and that of Ijolite is 5.5-6. The types of Evaporite are Sedimentary rock whereas types of Ijolite are Alkaline rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Ijolite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Ijolite is 0.84 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 Ijolite is heat resistant, impact resistant, wear resistant.
