Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

Evaporite vs Flint 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 Flint characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Flint. Learn more about Evaporite vs Flint in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Flint include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Evaporite and Flint, 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 Flint include Arrowheads, Cutting tool, Spear points.
More about Evaporite and Flint
Here you can know more about Evaporite and Flint. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Flint consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Flint includes Silicon. You can also check out the list of all Sedimentary Rocks. When we have to compare Evaporite vs Flint, 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, Flint is available in black, brown, green, grey, red, white colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Flint is Glassy or Pearly. Properties of rock is another aspect for Evaporite vs Flint. The hardness of Evaporite is 2-3 and that of Flint is 7. The types of Evaporite are Not Available whereas types of Flint 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 Flint is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Flint is 0.74 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 Flint is heat resistant, impact resistant, pressure resistant, wear resistant.
