Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Evaporite vs Migmatite 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 Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Migmatite. Learn more about Evaporite vs Migmatite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Evaporite and Migmatite, 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 Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Evaporite and Migmatite
Here you can know more about Evaporite and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Migmatite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Migmatite, 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, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Evaporite vs Migmatite. The hardness of Evaporite is 2-3 and that of Migmatite is 5.5-6.5. The types of Evaporite are Not Available whereas types of Migmatite are Diatexites and Metatexites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Migmatite is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Migmatite 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 Migmatite is heat resistant, pressure resistant.
