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

Abstract

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