Chalk and landscape of the South Downs, England
Authors:David Nowell
Institution:Hertfordshire, UK
Abstract:The Upper Cretaceous Chalk hills of the South Downs form the southern flank of the Wealden anticline in south-east England, with older Wealden and Purbeck sediments exposed at its core. With prominent chalk escarpments on each side of it, this major structure is up to 70 km wide, and extends eastwards for over 200 km from eastern Hampshire to the area around Boulogne-sur-Mer in Northern France, dissected by the English Channel.
