Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.

Evaporite vs Greenschist 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 Greenschist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Greenschist. Learn more about Evaporite vs Greenschist in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Greenschist include Bathrooms, Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Greenschist, 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 Greenschist include As dimension stone, Building houses or walls, Cement manufacture, Cutting tool, For road aggregate, Roadstone.
More about Evaporite and Greenschist
Here you can know more about Evaporite and Greenschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Greenschist consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Greenschist, 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, Greenschist is available in dark greenish - grey, green colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Greenschist is Layered and Shiny. Properties of rock is another aspect for Evaporite vs Greenschist. The hardness of Evaporite is 2-3 and that of Greenschist is 3.5-4. The types of Evaporite are Sedimentary rock whereas types of Greenschist are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Greenschist is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Greenschist 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 Greenschist is impact resistant, pressure resistant, water resistant.
