Formation
Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.

Oolite 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. Oolite vs Evaporite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oolite and Properties of Evaporite. Learn more about Oolite vs Evaporite in the next section. The interior uses of Oolite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Evaporite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Oolite and Evaporite, they have various applications in construction industry. The uses of Oolite in construction industry include Cement manufacture, Cobblestones, Landscaping 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 Oolite and Evaporite
Here you can know more about Oolite and Evaporite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oolite and Evaporite consists of mineral content and compound content. The mineral content of Oolite includes Calcite, Chert, Clay, Dolomite, Quartz, Sand, Silt 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 Oolite vs Evaporite, the texture, color and appearance plays an important role in determining the type of rock. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas, Evaporite is available in colourless, green, grey, silver, white colors. Appearance of Oolite is Rounded and Rough and that of Evaporite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Oolite vs Evaporite. The hardness of Oolite is 3-4 and that of Evaporite is 2-3. The types of Oolite 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 Oolite and Evaporite is white. The specific heat capacity of Oolite is Not Available 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.Oolite is heat resistant, wear resistant whereas Evaporite is heat resistant, pressure resistant.
