One only has to mention that oolitic limestone is made up of oolites and someone will pipe up "Well, what's an oolite then?" Oolites are specs of matter (often organic) that have been coated in limestone to form a small limestone grain.
Oolitic limestone is a finely granular sedimentary rock made from billions of oolites. Without magnification an oolite looks like this: ".".
The first dot represents an oolite, and the second dot represents the termination of the sentence. Further dots are syntactic and not oolitic. For the etymologically minded, we have oion (Gr.), an egg, and lithos (Gr.), a stone - apparently someone thought the granularity of oolitic limestone resembled fish roe. Oolitic limestone does not appear to form the caverns and sinkholes common in many limestone areas, but it does make fine building stone .
The picture above shows exposed limestone in an abandoned quarry on the Cotswold Edge near Wotton Under Edge.
