Staithes Sandstone Formation

Computer Code: STA Preferred Map Code: Sta
Status Code: Full
Age range: Pliensbachian Age (JE) — Pliensbachian Age (JE)
Lithological Description: Silty sandstone, more or less argillaceous, typically intensely bioturbated and/or showing bedding structures of many types.
Definition of Lower Boundary: Gradational contact with underlying mudstones of the Redcar Mudstone Formation, but defined at base of "Oyster Bed" (highly fossiliferous calcareous and ferruginous sandstone), which apparently persists as a continuous horizon throughout the Cleveland Basin.
Definition of Upper Boundary: Upward transition from sandstone/siltstone to shaly mudstone with scattered sideritic nodules of the Cleveland Ironstone Formation.
Thickness: To c.30m
Geographical Limits: Cleveland Basin, North Yorkshire.
Parent Unit: Lias Group (LI)
