The non-marine Lower Cretaceous Wealden strata of southern England

The non-marine Lower Cretaceous Wealden strata of the Wessex-Weald Basin (southern England) are introduced, with reference to the depositional model developed by Professor Percival Allen FRS (Allen, 1975). To demonstrate this model and the development of Wealden palaeoenvironments through time, Wealden sites have been selected for the Geological Conservation Review programme. Site selection rationale is briefly outlined.
