Reworked palynomorphs from the Red Crag and Norwich Crag formations (EarlyPleistocene) of the Ludham Borehole, Norfolk

Early Pleistocene estuaries in Norfolk and Suffolk were supplied by at leas t three large rivers which transported elastic material from several Carbon iferous to Palaeogene formations in southern, central and northeastern Engl and. New palynological data on eight samples from the Pleistocene Crag Grou p (Red Crag and Norwich Crag formations) of the Ludham Borehole, Norfolk; a dd significant detail to this palaeogeographical reconstruction, revealing the consistent presence of reworked palynomorphs of Carboniferous, Jurassic , Cretaceous and Palaeogene age. The presence of these allochthonous palyno morphs is attributed to fluvial debris from a major river which flowed into Norfolk from the west and northwest. The provenance of the sediment supply can be frequently identified to formational level.
