Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Evaporite vs Anthracite 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 Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Anthracite. Learn more about Evaporite vs Anthracite in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Evaporite and Anthracite, 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 Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Evaporite and Anthracite
Here you can know more about Evaporite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Anthracite consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Anthracite, 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, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Evaporite vs Anthracite. The hardness of Evaporite is 2-3 and that of Anthracite is 1-1.5. The types of Evaporite are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. 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 Anthracite is black. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
