Implications of a Middle Pleistocene ice-wedge cast at Trimingham, Norfolk, Eastern England

Auteur :
WHITEMAN, C.

Description :
A wedge exposed at Trimingham, northeast Norfolk, in 1998 is interpreted as an ice-wedge pseudomorph indicating that permafrost was present in the surrounding Cromer Foest-bed Formation sediments. The wedge is overlain by North Sea Drift Formation (NSDF) glacial sediments, demonstrating that the associated ice sheet deposited till in either a terrestrial or an extremely shallow glaciolacustrine/marine environment. This conclusion supports those who believe that this ice sheet was, at least initially, terrestrial at this location.
