Formation
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Taconite 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. Taconite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Evaporite. Learn more about Taconite vs Evaporite in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, 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 Taconite and Evaporite, they have various applications in construction industry. The uses of Taconite in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. 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 Taconite and Evaporite
Here you can know more about Taconite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Evaporite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Taconite vs Evaporite. The hardness of Taconite is 5.5-6 and that of Evaporite is 2-3. The types of Taconite 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 Taconite and Evaporite is white. The specific heat capacity of Taconite is 3.20 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.Taconite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
