The town of Oolitic, Indiana, was founded for the trade in limestone and bears its name. Quarries in Oolitic, Bedford, and Bloomington contributed the materials for such U.S. landmarks as the Empire State Building in New York and the Pentagon in Arlington, Virginia.
Oolitic may refer to: Oolite, a sedimentary rock consisting of ooids; Oolitic, Indiana, a town whose name came from the underlying limestone; Oolitic aragonite sand, which is formed naturally, and used extensively in reef aquariums
The technical geologic term for most oolitic limestones is “oolitic grainstone”. Uncertainty exists about the specifics of the origin of oolites. Some researchers conclude that oolites form by completely inorganic chemical precipitation of CaCO3 from water around some nucleus (a tiny shell or skeletal fragment or sediment grain).
Ooids usually form on the sea floor, most commonly in shallow tropical seas (around the Bahamas, for example, or in the Persian Gulf). After being buried under additional sediment, these ooid grains can be cemented together to form a sedimentary rock called an oolite.

Great Pulteney Street, Bath, looking West towards Pulteney Bridge.The style and the Bath stone used are typical of much of the city. Bath stone is an oolitic limestone comprising granular fragments of calcium carbonate originally obtained from the Middle Jurassic aged Great Oolite Group of the Combe Down and Bathampton Down Mines under Combe Down, Somerset, England.
The part of the Miami Limestone forming the Atlantic Coastal Ridge and the lower Florida Keys is an oolitic grainstone which includes fossils of corals, echinoids, mollusks, and algae. The oolitic formation in the lower Florida Keys has less quartz sand and fewer fossils than does the oolitic formation on the mainland. [3]
Sample of fossiliferous limestone Examples of small fossils in limestone Fossiliferous limestone is a type of limestone that contains noticeable quantities of fossils or fossil traces . If a particular type of fossil dominates, a more specialized term can be used as in " Crinoidal ", "Coralline", "Conchoidal" limestone.
