Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

Evaporite vs Oil shale 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 Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Evaporite and Properties of Oil shale. Learn more about Evaporite vs Oil shale in the next section. The interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Evaporite and Oil shale, 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 Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Evaporite and Oil shale
Here you can know more about Evaporite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Evaporite and Oil shale consists of mineral content and compound content. The mineral content of Evaporite includes Calcite, Cancrinite, Gypsum, Kyanite, Magnetite and mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all . When we have to compare Evaporite vs Oil shale, 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, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Evaporite is Glassy, Vesicular and Foilated and that of Oil shale is Muddy. Properties of rock is another aspect for Evaporite vs Oil shale. Hardness of Evaporite and Oil shale is 2-3. The types of Evaporite are Not Available whereas types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Evaporite and Oil shale is white. The specific heat capacity of Evaporite is 0.92 kJ/Kg K and that of Oil shale is 0.39 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 Oil shale is heat resistant, impact resistant.
