- Coral rag
-
Coral rag is a rubbly limestone composed of ancient coral reef material. The term also refers to the building blocks quarried from these strata which are an important local building material in areas such as the east African coast and the Caribbean basin (e.g., Bermuda, Florida).
It is also the name of a member — the Coral Rag Member — of the Upper Oxfordian Coralline Oolite Formation of North Yorkshire, England.
