Elster glaciation


The Elster glaciation or, less commonly, the Elsterian glaciation, in the older and popular scientific literature also called the Elster Ice Age, is the oldest known ice age that resulted in the large-scale glaciation of North Germany. It took place 500,000–300,000 years ago. It succeeded a long period of rather warmer average temperatures, the Cromerian Complex. The Elster was followed by the Holstein interglacial and the Saale glaciation. The glacial period is named after the White Elster, a right tributary of the Saale.

Controversial correlations

Traditionally, Elster was correlated with the Mindel glaciation of the Alps and the Anglian glaciation of Great Britain and Ireland. Analysis in the 1950s of oxygene isotopes in deep sea core samples introduced a global glacial history, with warm and cold phases identified by marine isotope stages. This identified two glacial stages in the time slot of the Elster/Mindel/Anglian, namely MIS 12 and MIS 10. A lack of suitable isotopes for dating the glacial deposits has made it difficult to resolve the ambiguity. This has led to an increasingly controversial issue between the two main alternatives:
