Geology and Geography of the London–North Sea Uplands in Wealden Times

Abstract

AbstractThe uplands seem to have consisted of an interior highland north of the Thames made principally of Upper Palaeozoic rocks, and a marginal vale-and-scarp lowland of Jurassic strata on the south. This lowland bordered the Wealden morass. Much of the highland exceeded 1,000 feet. It was probably a high-level peneplain resurrected by end-Purbeck earth-movements. Two main rivers entered the swamps and account for most of the detritus. Their probable relations recall those of the contemporary rivers in Belgium.
