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

Etymology
From a sediment left after the evaporation
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color

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.

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 colourless, 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 Not Available whereas types of Greenschist are Not Available. 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 Not Available. 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.
