Answer :
Final answer:
Oolitic limestones form in a shallow-marine environment. They are composed of sand-sized, well-rounded carbonate particles called ooliths, which have concentric layers. Oolitic limestones are typically found in shallow, wave-agitated waters. The correct answer is A.
Explanation:
The correct answer is A. Oolitic Limestones. Oolitic limestones form in a shallow-marine environment. They are composed of sand-sized, well-rounded carbonate particles called ooliths, which have concentric layers.
Ooliths are formed in shallow, wave-agitated waters and they become cemented together to form oolitic limestone.
For example, in Figure 5.29, the geologists have identified oyster shells among large blocks on a beach. Oyster shells are common in shallow-marine environments and can be found in oolitic limestones. The correct answer is A.
