Bath Oolite Formation
The Great Oolite Group is a Middle Jurassic Stratigraphy, stratigraphic unit that outcrops in southern England. It consists of a complex set of marine deposits primarily mudstone and Bioclast, bioclastic Ooid, ooidal and Grain size, fine grained limestone, deposited in Littoral zone, nearshore to Continental shelf, shelf settings. It is exposed at the surface as a variably thick belt extending roughly NE-SW from the coast of Dorset up to the Humber. It is also present at depth in the Weald Basin, Weald and Wessex Basins, as well as offshore. Several of the constituent formations, notably the Taynton Limestone Formation and the Forest Marble Formation are notable for their fossil content, including those of dinosaurs and pterosaurs and some of the earliest mammals.

Combe Down And Bathampton Down Mines
Combe Down and Bathampton Down Quarries () make up a 6.22 hectare (15.37 acre) Site of Special Scientific Interest (SSSI) in Bath and North East Somerset, England, important for its bat population. The disused quarries date from the 17th and 18th centuries and were the source of Bath stone for the city of Bath and elsewhere in the UK. A five-year project to stabilise the quarry workings was largely completed by November 2009. Geology Combe Down forms a plateau capped by Great Oolite limestones between the valley of the River Avon and Horsecombe Vale. The geology of the region is dominated by rocks of Middle and Early Jurassic ages. The Great Oolite is the uppermost lithology, underlain by the clays of the Fuller's Earth Formation, which in turn is underlain by limestones of the Inferior Oolite and the Midford Sands of the Lias. The Great and Inferior Oolite formations provide effective aquifers (rock in which water can be stored and pass through) for public and private water ...
