Oolitic limestone texture.
Feb 1, 1987 · On the other hand, the number of environmental processes is generally low and the compositional maturity high on mobile oolite shoals, beaches, tidal flats and sabkhas, and in deep-water basins. Application of compositional maturity in carbonate-facies analysis, therefore, focuses attention on sedimentary processes in the depositional environment.

They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow seafloor. Oolite or oölite (egg stone) is a sedimentary rock formed from ooids, spherical grains composed of concentric layers.
The Indiana Limestone Institute grade classifications are determined by how fine or coarse the grain particles and other natural characteristics that comprise the limestone. Oolitic and fossiliferous limestones appear in all grades of limestone. The structural soundness of each classification of limestone is essentially identical.
