Dean Hill Anticline
The Dean Hill Anticline is an east-west trending fold in the Cretaceous chalk of Hampshire. It lies immediately to the north of the Hampshire Basin and south of Salisbury Plain.
Structure[]
The anticline runs west 15 kilometres (9.3 mi) from the River Test near Lockerley along the northern rim of the Hampshire Basin, to the south of a narrow strip of palaeogene rocks, the Alderbury-Mottisfont Syncline.[1][2] At the eastern end under the Test Valley it is cut by the northward-swinging Portsdown Anticline. At the western end to the south-east of Salisbury the structure is cut by the Mere Fault.[3]
In the core the Santonian Newhaven Chalk Formation reaches the surface.[1][2] In the outer limits near Whiteparish chalk as young as the Campanian Portsdown Chalk Formation is found.
Hills include Witherington Down, Pepperbox Hill and Dean Hill.
