The Weald–Artois Anticline, or Wealden Anticline, is a large anticline, a geological structure running between the regions of the Weald in southern England and Artois in northern France. The fold formed during the Alpine orogeny, from the late Oligocene to middle Miocene as an uplifted form of the Weald basin through inversion of the basin.
The geological map shows the High Weald in lime green (9a). The Low Weald, [18] the periphery of the Weald, is shown as darker green on the map (9), [19] and has an entirely different character. It is in effect the eroded outer edges of the High Weald, revealing a mixture of sandstone outcrops within the underlying clay.
The Weald Basin has yielded significant quantities of gypsum from Jurassic Purbeck beds and a number of brickworks exploit the lower Cretaceous clays. The inversion of the Weald Basin throughout the late Cretaceous and early Tertiary resulted in the formation of the Wealden Anticline and a number of smaller anticlines within the larger structure.
The geology of East Sussex is defined by the Weald–Artois anticline, a 60 kilometres (37 mi) wide and 100 kilometres (62 mi) long fold within which caused the arching up of the chalk into a broad dome within the middle Miocene, [1] which has subsequently been eroded to reveal a lower Cretaceous to Upper Jurassic stratigraphy.

A map showing the hypothetical extent of Doggerland from now back to the Weichselian glaciation. Until the middle Pleistocene, Great Britain was a peninsula of Europe, connected by the massive chalk Weald–Artois Anticline across the Strait of Dover.
More recently, a World Ortelius map sold for £4,000 (about $5,000) at an auction in 2012. These maps are celebrated for their artistry and the way they reflect the geographical knowledge of the ...
