Lithological Description: |
Limestones and clayey limestones intercalated with lime-rich muds and clays. Includes impersistent peloidal limestones and calcretes. |
Definition of Lower Boundary: |
The basal contact is gradational or sharp and erosive into principally silts and clays within the members of the underlying Headon Hill Formation. |
Definition of Upper Boundary: |
Gradational or sharp contact with clays and silts of the Bembridge Marls Member (Bouldnor Formation). As originally defined (Insole and Daley, 1985) the formation included about 2m of lime-rich clays and clay above the highest limestone. These are now assigned to the overlying Bembridge Marls Member (Bouldnor Formation) by Daley and Edwards (1990). |
Thickness: |
Up to 9m. |
Geographical Limits: |
Throughout the northern part of the Isle of Wight. |
Parent Unit: |
Solent Group (SOLT)

Type Section |
Cliff section at Whitecliff Bay, Isle of Wight where 8.5m of pale brown to white fossiliferous limestones and lime-rich mudstones in three cycles are seen. Daley and Edwards (1990); Insole and Daley (1985). |
