Oolitic limestone texture.

Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.

Oolitic limestone is made up of small spheres called ooiliths that are stuck together by lime mud. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor.Oolitic limestone has a unique texture characterized by the presence of ooids, which give the rock a granular, sometimes sandy appearance. The size of the ooids can vary, but they are typically between 0.25 and 2 millimeters in diameter.Limestone forms through the accumulation and compaction of marine organisms, primarily the remains of shellfish and coral, over millions of years.
