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.

All about Oolite and Evaporite Properties

Know all about Oolite and Evaporite properties here. All properties of rocks are important as they define the type of rock and its application. Oolite and Evaporite belong to Sedimentary Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Evaporite is Earthy. Oolite appears Rounded and Rough and Evaporite appears Glassy, Vesicular and Foilated. The luster of Oolite is pearly to shiny while that of Evaporite is subvitreous to dull. Oolite and Evaporite are available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite.
