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

Flint 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. Flint vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Flint and Properties of Evaporite. Learn more about Flint vs Evaporite in the next section. The interior uses of Flint include Decorative aggregates, 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 Flint and Evaporite, they have various applications in construction industry. The uses of Flint in construction industry include Arrowheads, Cutting tool, Spear points 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 Flint and Evaporite
Here you can know more about Flint and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Evaporite consists of mineral content and compound content. The mineral content of Flint includes Silicon 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 Flint vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Flint is Glassy or Pearly and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Flint vs Evaporite. The hardness of Flint is 7 and that of Evaporite is 2-3. The types of Flint 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 Flint and Evaporite is white. The specific heat capacity of Flint is 0.74 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.Flint is heat resistant, impact resistant, pressure resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
