It is also to be found beneath the scarp of the Berkshire Downs, in the Vale of White Horse, in Oxfordshire, England, and on the Isle of Wight where it is known as Blue Slipper.

[4] Gault underlies the chalk beneath the London Basin, generally overlying eroded rocks of Jurassic and Devonian age; lower gault is present only below the outer parts of the basin and is absent under central London.

The Gault Formation thins across the London Platform and then terminates against the Red Chalk just to the south of The Wash in East Anglia.

[citation needed] Gault often contains numerous phosphatic nodules, some thought to be coprolites, and may also contain sand as well as small grains of the mineral glauconite.

Gault yields abundant marine fossils, including ammonites (such as Hoplites, Hamites, Euhoplites, Anahoplites, and Dimorphoplites), belemnites (such as Neohibolites), bivalves (such as Birostrina and Pectinucula), gastropods (such as Anchura), solitary corals, fish remains (including shark teeth), scattered crinoid remains, and crustaceans (such as the crab Notopocorystes).
