The Peterborough Member (Callovian, Middle Jurassic) of the Oxford Clay Formation at Peterborough, UK

King’s Dyke brick pit, Whittlesey, near Peterborough, Cambridgeshire, provides a continuous section through the Peterborough Member (formerly known as the Lower Oxford Clay) of the Oxford Clay Formation, and is here described as its type section. It also shows parts of the underlying Kellaways Formation and of the overlying Stewartby Member of the Oxford Clay Formation. Other sections in the Peterborough district are discussed and related to the type section. The Peterborough Member is developed throughout southern England and aspects of its stratigraphy, palaeogeography and burial history are briefly reviewed.
