Cromerian

An Interglacial Stage of northern Europe correlated with the Günz-Mindel Interglacial, part of the series of interglacials recognized in Britain: the Pastonian (oldest), Beestonian, and Cromerian. The Cromerian stage is a group of Interglacial deposits of the Quaternary system which are stratified under Anglian glacial deposits and above an extensive sequence of earlier Quaternary deposits. The type site of the stage is at West Runton, Norfolk. In northwest Europe, a group of deposits representing several interglacials and intervening cold stages, and these deposits are stratified below Elster glacial deposits and above a sequence extending back into the Pliocene.

The Cromerian stage is a group of interglacial deposits of the Quaternary system in Britain. These deposits are stratified under Anglian glacial deposits and above an extensive sequence of earlier Quaternary deposits. The type site of the stage is at West Runton, Norfolk, but a number of other deposits have been correlated with it — from Suffolk, Oxfordshire and Somerset. Confusion may arise from the use of ‘Cromerian Complex’ to describe part of the Quaternary succession in northwest Europe. In this case, the term is used to describe a group of deposits representing several interglacials and intervening cold stages. These deposits are stratified below Elster glacial deposits and above a sequence extending back into the Pliocene. The Brunhes/Matuyama boundary of c700,000 bp (see palaeomagnetism) occurs within the European ‘Cromerian Complex’, but it is unclear how these deposits should be correlated with the Quaternary of Britain.
