Coralline Oolite Formation


The Coralline Oolite Formation is a limestone formation of Oxfordian age, found in the Cleveland Basin of North Yorkshire, England.

Coral Rag Member

The rock forms some of the hills around Oxford and was once used as building stone. Coral rag can be seen in some of the oldest buildings in that city, including the Saxon tower of St Michael at the Northgate, St George's Tower of Oxford Castle and the mediaeval walls of the city.

Hambleton Oolite Member

This ooidal limestone lies above either the Yedmandale Member or the Lower Calcareous Grit Formation. It is overlain by either the Middle Calcareous Grit or Malton Oolite Members. It is distinguished from the latter by its smaller grain-size and poorer sorting.
