Norwich Crag Formation, Geological formation in East Anglia, Great Britain
The Norwich Crag Formation is a geological layer in East Anglia made up of fine to medium sand deposits with glauconitic and micaceous materials mixed throughout. These sediments spread across Norfolk and Suffolk, revealing how this part of England was shaped by ancient depositional processes.
This layer formed roughly 2.4 to 1.8 million years ago during a period when climate and sea levels shifted significantly around Britain. The deposits represent a time that shaped the geology of eastern landscapes in lasting ways.
Scientists at the British Geological Survey have studied this formation extensively since 1975, establishing its importance in understanding regional stratigraphy.
You can view these formations at several spots in Suffolk, particularly near Wickham Market and Aldeburgh, where the layers are exposed. The best visits happen at locations where natural or human-made cuts reveal the inner layers clearly.
The layer contains remains of extinct animals such as proboscideans, horses, and marine mammals, showing how diverse the habitats of that time were. These fossils help scientists understand that this region once held coastal forests and shallow seabeds.
