Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Evaporite vs Scoria 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 Scoria characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Scoria. Learn more about Evaporite vs Scoria in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Scoria include Decorative aggregates and Interior decoration. Due to some exceptional properties of Evaporite and Scoria, 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 Scoria include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works.
More about Evaporite and Scoria
Here you can know more about Evaporite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Scoria consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Evaporite vs Scoria. The hardness of Evaporite is 2-3 and that of Scoria is 5-6. The types of Evaporite are Not Available whereas types of Scoria are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Scoria is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Scoria 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 Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
