Definition
A water-soluble mineral sediment resulting from concentration and crystallization by evaporation from an aqueous solution
  
Skarns are formed during regional or contact metamorphism and from a variety of metasomatic processes involving fluids of magmatic, metamorphic, and/or marine origin

Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
  
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Skarn is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Evaporite vs Skarn 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 Skarn characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Skarn. Learn more about Evaporite vs Skarn in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Skarn include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Evaporite and Skarn, 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 Skarn 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, Gold and silver production, Manufacture of magnesium and dolomite refractories.
More about Evaporite and Skarn
Here you can know more about Evaporite and Skarn. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Skarn consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Skarn includes Calcite, Enstatite, Epidote, Garnet, Magnetite, Pyroxene, Titanite. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Skarn, 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, Skarn is available in black, brown, colourless, green, grey, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Skarn is Dull. Properties of rock is another aspect for Evaporite vs Skarn. The hardness of Evaporite is 2-3 and that of Skarn is 6.5. The types of Evaporite are Not Available whereas types of Skarn are Endoskarns. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite is white while that of Skarn is light to dark brown. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Skarn 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.Evaporite is heat resistant, pressure resistant whereas Skarn is heat resistant.
