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. Alexanderson pointed out that in an environment of undersaturated sea water, micritization does not take place and early diagenetic changes will be destructive ...
