Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.

Evaporite vs Banded iron formation 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 Banded iron formation characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Banded iron formation. Learn more about Evaporite vs Banded iron formation in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Banded iron formation include Decorative aggregates and Homes. Due to some exceptional properties of Evaporite and Banded iron formation, 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 Banded iron formation include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Evaporite and Banded iron formation
Here you can know more about Evaporite and Banded iron formation. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Banded iron formation consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all . When we have to compare Evaporite vs Banded iron formation, 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, Banded iron formation is available in red, reddish brown colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Evaporite vs Banded iron formation. The hardness of Evaporite is 2-3 and that of Banded iron formation is 5.5-6. The types of Evaporite are Not Available whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Banded iron formation is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Banded iron formation is 3.20 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 Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
