Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Pyrolite 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 Pyrolite 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 Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Pyrolite. Learn more about Evaporite vs Pyrolite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Evaporite and Pyrolite, 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 Pyrolite include As dimension stone, Cobblestones.
More about Evaporite and Pyrolite
Here you can know more about Evaporite and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Pyrolite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Pyrolite, 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, Pyrolite is available in dark greenish - grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Evaporite vs Pyrolite. The hardness of Evaporite is 2-3 and that of Pyrolite is 5.5-6. The types of Evaporite are Sedimentary rock whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Pyrolite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Pyrolite is 1.25 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 Pyrolite is heat resistant, pressure resistant, wear resistant.
