Geology of Kent the northern slopes of the Downs where they are known as brickearths. Landslips are known along the north coast of the Isle of Sheppey, the coast near Reculver and either side of Folkestone and indeed the former coastline west of Folkestone overlooking Romney Marsh. Geology of Kent The geology of Kent in southeast England largely consists of a succession of northward dipping late Mesozoic and Cenozoic sedimentary rocks overlain by a suite of unconsolidated deposits of more recent origin. Kent is the south-easternmost county in England. It is bounded on the north by the River Thames and the North Sea,
Whitstable and South Street at the south. Chestfield has its own parish council. An area of protected woodland and grassland called Duncan Down lies to the south-east. The geology of the town consists mainly of London Clay (which covers most of North Kent). Much of the centre of the town is built on low-lying marshland. Sea walls are in place to prevent coastal flooding. The land in the east is higher, with slopes down to the coast at Tankerton. The whole of the north-east Kent coast has been designated a Site of Special Scientific Interest. A very unusual (some say unique)
