Chalk Group Lithostratigraphy: East Anglia - Totternhoe Stone

The Totternhoe Stone (= Burwell Rock of the Cambridge district) is as described in the adjacent Chilterns region. It is a brownish, gritty, shell-rich calcarenitic chalk bed, typically with phosphatic nodules at its base, with a conspicuous, and locally strongly down-cutting basal erosion surface. In parts of East Anglia (eg. Cambridge district) it forms a strong topographical feature (Worssam & Taylor, 1969). Around Cambridge it is c. 6 m thick, but thins northward across the region to c. 1.5 m in south Norfolk, and c. 0.7 m thick at Hunstanton in north Norfolk (Worssam & Taylor, 1969; Peake & Hancock, 1970; Gallois, 1994).
