Sedimentary environments associated with Glacial Lake Trimingham, Norfolk, UK
The site of Trimingham is situated where the Cromer Ridge, the largest topographic feature of northeast Norfolk, transects the coastline, providing an opportunity to study the ridge's internal structure and stratigraphy. It can be demonstrated that there were two glacial advances at this site,...

The site of Trimingham is situated where the Cromer Ridge, the largest topographic feature of northeast Norfolk, transects the coastline, providing an opportunity to study the ridge's internal structure and stratigraphy. It can be demonstrated that there were two glacial advances at this site, with an intervening phase of proglacial lake sedimentation that lasted for approximately 2000 years (Glacial Lake Trimingham). A detailed investigation of the sedimentology of the lake sediments enabled a facies reconstruction showing spatial and temporal changes within this lake. Ice‐sheet retreat is indicated by an upward change from proximal to distal varve sequences, and a general shallowing of the lake followed by the deposition of marl‐rich sediments and then aeolian and/or beach sands.
