Cross-bedding and grain-size distribution in the lower Cretaceous Woburn sands, lying between Cambridge and Leighton Buzzard, in southeast England, were investigated in detail, and the Sandringham sands between Downham and Hunstanton examined briefly. The largescale cross-bedding of the Woburn sands is taken to indicate submarine delta formation, with an east-west shore line lying to the north during Aptian time. Other paleogeographic conditions are suggested.
