Formation
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Phyllite 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. Phyllite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phyllite and Properties of Evaporite. Learn more about Phyllite vs Evaporite in the next section. The interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Phyllite and Evaporite, they have various applications in construction industry. The uses of Phyllite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone 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 Phyllite and Evaporite
Here you can know more about Phyllite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phyllite and Evaporite consists of mineral content and compound content. The mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon 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 Phyllite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Phyllite is available in black to grey, light greenish grey colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Phyllite is Crinkled or Wavy and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Phyllite vs Evaporite. The hardness of Phyllite is 1-2 and that of Evaporite is 2-3. The types of Phyllite 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 Phyllite and Evaporite is white. The specific heat capacity of Phyllite 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.Phyllite is heat resistant, pressure resistant, water resistant whereas Evaporite is heat resistant, pressure resistant.
