A review of the Chalk of the Northern Province recognizes six formations, five of which (Hunstanton, Ferriby, Welton, Burnham and Flamborough formations) crop out in northern Norfolk, Lincolnshire and Yorkshire, and a sixth (Rowe Formation) is buried beneath the drift of Holderness. The Hunstanton, Ferriby and Flamborough formations are largely devoid of flints, whereas the Welton (other than its two basal members) and Burnham formations have nodular and tabular flints, respectively. Previous work on the lithostratigraphy and marker beds is presented, and an overview of the distribution of the more important macrofossils is provided. Especial attention is given to the succession at Speeton through the Hunstanton, Ferriby and lower Welton formations with details of the oxygen and carbon isotope signatures. The Speeton section is internationally important because of its expanded Albian-Mid Cenomanian succession. Small sections of the Burnham Formation in Speeton–Buckton cliffs are also presented for the first time. The appendix reviews the relevant Cretaceous stage boundaries with reference to the Chalk of the Northern Province together with details of the fossil zones that are used in this paper.
