Polyphase glacitectonic deformation during possible active retreat, Weybourne Town Pit

The significance of the inter‐stratified tills exposed in the Weybourne area of North Norfolk has attracted much attention and various scenarios have been proposed for their development (Banham and Ranson, 1965; Bowen et al., 1986; Fish et al., 2000; Pawley et al., 2004; Hart, 2007). This debate highlights the ambiguity of interpreting inter‐stratified till sequences where the mechanisms proposed range from: (1) the confluence of different ice sheets (Ehlers and Gibbard, 1991; Lunkka, 1994); a sedimentary ‘melt‐out’ origin (Haldorsen and Shaw, 1982) and glacitectonic processes associated with a subglacial deforming bed (Hart et al., 1990; van der Meer et al., 2003; Menzies et al., 2006).
