Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
  
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Eclogite vs Evaporite 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. Eclogite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Evaporite. Learn more about Eclogite vs Evaporite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Evaporite, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used and that of Evaporite 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.
More about Eclogite and Evaporite
Here you can know more about Eclogite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Evaporite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Eclogite vs Evaporite. The hardness of Eclogite is 3.5-4 and that of Evaporite is 2-3. The types of Eclogite are Not Available whereas types of Evaporite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Evaporite is white. The specific heat capacity of Eclogite is Not Available and that of Evaporite 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.Eclogite is heat resistant whereas Evaporite is heat resistant, pressure resistant.
