Trimingham : structural architecture of the Cromer Ridge Push Moraine complex and controls for landslide geohazards

摘要

One of the most striking geomorphological features of the north Norfolk area is the Cromer Ridge. Itudextends eastwards from Thursford, near Fakenham, to Trimingham where it intersects the North Seaudcoast. The ridge has been interpreted in‐part, as a push moraine formed at the southern margins ofudthe Middle Pleistocene ice sheet and is draped on its ice‐distal southern flank by extensive spreadsudof outwash sand and gravel (Hart, 1990; Pawley et al., 2005). Coastal sections between Triminghamudand Overstrand offer a rare opportunity to examine the internal architecture of this structure. Theudfocus of this chapter is to document the structural geology of this landform, and examine theudinfluence of its structure on coastal stability and landslide geohazards.
