Present in Brown Moor Borehole, SE86SW/4 (Gaunt et al., 1980). Non-sequence/unconformity: rubbly coralliferous shelly limestone (Coral Rag Member) sharply overlain by silty mudstone and fine-grained sandstone (Newbridge Member) or fine-grained calcareous sandstone (Spaunton Sandstone Member) or unfossiliferous fine-grained limestone (North Grimston Cementstone Member) or clayey sandstone (Limekiln Member, all of Upper Calcareous Grit Formation), or where the Upper Calcareous Grit is absent in the south, by mudstone of the Ampthill Clay Formation, or red chalk of the Hunstanton Formation.ģ6m (Filey-Scarborough area), 60 m (Tabular Hills), 50 m (Hambleton Hills-Howardian Hills).Ĭleveland Basin, North Yorkshire: as far south as Acklam area, where overstepped by Cretaceous strata. Non-sequence: generally well-cemented calcareous fine-grained sandstone, locally spicule-rich (Lower Calcareous Grit Formation), or where absent, grey silty mudstone (Weymouth Member, Oxford Clay Formation), sharply overlain by softer fine- to medium-grained calcareous sandstone (basal Yedmandale Member or Birdsall Calcareous Grit Member) or sandy ooidal limestone (Hambleton Oolite Member).
Locally a fine-grained peloidal limestone is developed (Hildenley Limestone Member). Other fauna notably ammonites, bivalves and gastropods. Limestone, variably ooidal, shelly, coralliferous and bioclastic (Yedmandale (part), Hambleton Oolite, Malton Oolite and Coral Rag members) interbedded with, and passing laterally into fine-grained sandstone, variably calcareous, shelly and bioturbated (Yedmandale (part), Birdsall Calcareous Grit and Middle Calcareous Grit members), sponge spicules abundant at some levels.
