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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

All about Oolite and Laterite Properties
Know all about Oolite and Laterite properties here. All properties of rocks are important as they define the type of rock and its application. Oolite and Laterite belong to Sedimentary Rocks.Texture of Oolite is Clastic or Non-Clastic whereas that of Laterite is Earthy, Massive, Porphyritic. Oolite appears Rounded and Rough and Laterite appears Rough and Banded. The luster of Oolite is pearly to shiny while that of Laterite is dull. Oolite is available in black, blue, brown, cream, green, grey, pink, red, silver, white, yellow colors whereas Laterite is available in brown, buff, red colors. The commercial uses of Oolite are creating artwork, jewelry, used in aquariums and that of Laterite are an oil and gas reservoir, source of bauxite, used in aquariums.
