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

Metapelite 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. Metapelite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Metapelite and Properties of Evaporite. Learn more about Metapelite vs Evaporite in the next section. The interior uses of Metapelite 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 Metapelite and Evaporite, they have various applications in construction industry. The uses of Metapelite in construction industry include Cement manufacture, Construction aggregate, For road aggregate 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 Metapelite and Evaporite
Here you can know more about Metapelite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Evaporite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz 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 Metapelite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Metapelite is Banded and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Metapelite vs Evaporite. The hardness of Metapelite is 5-6 and that of Evaporite is 2-3. The types of Metapelite 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 Metapelite is unknown while that of Evaporite is white. The specific heat capacity of Metapelite is 0.72 kJ/Kg K 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Evaporite is heat resistant, pressure resistant.
