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.
Section across southern England showing the inverted nature of the Weald Basin. The Weald Basin (/ ˈ w iː l d /) is a major topographic feature of the area that is now southern England and northern France from the Triassic to the Late Cretaceous. Its uplift in the Late Cretaceous marked the formation of the Wealden Anticline.
The Wadhurst Clay Formation is a geological unit which forms part of the Wealden Group and the middle part of the now unofficial Hastings Beds.These geological units make up the core of the geology of the High Weald in the English counties of West Sussex, East Sussex and Kent.
The Tunbridge Wells Sand Formation is a geological unit which forms part of the Wealden Group and the uppermost and youngest part of the unofficial Hastings Beds.These geological units make up the core of the geology of the Weald in the English counties of West Sussex, East Sussex and Kent.
The Ashdown Formation is a geological unit, which forms part of the Wealden Group and the lowermost and oldest part of the now unofficial Hastings Beds.These geological units make up the core of the Weald in the English counties of East Sussex and Kent.
Weald Clay or the Weald Clay Formation is a Lower Cretaceous sedimentary rock unit underlying areas of South East England, between the North and South Downs, in an area called the Weald Basin. It is the uppermost unit of the Wealden Group of rocks within the Weald Basin, and the upper portion of the unit is equivalent in age to the exposed ...
