The Elster glaciation (german: Elster-Kaltzeit, ''Elster-Glazial'' or ''Elster-Zeit'') or, less commonly, the Elsterian glaciation, in the older and popular scientific literature also called the Elster Ice Age (''Elster-Eiszeit''), is the oldest known

Saale glaciation The Saale glaciation or Saale Glaciation, sometimes referred to as the Saalian glaciation, Saale cold period (german: Saale-Kaltzeit), Saale complex (''Saale-Komplex'') or Saale glacial stage (''Saale-Glazial'', colloquially also the ''Saale-Eiszei ...

Controversial correlations

Traditionally, Elster was correlated with the
Mindel glaciation The Mindel glaciation (german: Mindel-Kaltzeit, also ''Mindel-Glazial'', ''Mindel-Komplex'' or, colloquially, ''Mindel-Eiszeit'') is the third youngest glacial stage in the Alps. Its name was coined by Albrecht Penck and Eduard Brückner, who nam ...

s (MIS). 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: * MIS 12, 478–424 ka ago, is globally the stronger of the two glacials and long the preferred correlation to Elster/Mindel/Anglian. There is strong evidence for widespread glaciation of Great Britain during MIS 12, and only disputed and weak signs of glaciation during MIS 10.Lee et al. (2011), The Glacial History of the British Isles during the early and Middle Pleistocene: Implications for the long-term development of the British Ice Sheet, Quaternary Glaciations-Extent and Chronology, pages 59–74, Elsevier.
/ref> Thus, the correlation of the Anglian glaciation to MIS 12 is uncontroversial. The glacial history of Europe is much simplified if also Elster and Mindel are correlated to MIS 12. The Subcommission on Quaternary Stratigraphy (SQS) of the International Commission on Stratigraphy (ICS), a scientific organisation within the International Union of Geological Sciences (IUGS), correlates both the Anglian and the Elsterian to MIS 12 in the 2011 version of its correlation table.Subcommission on Quaternary Stratigraphy, Global chronostratigraphical correlation table for the last 2.7 million years, v. 2011
/ref> * MIS 10, 374–337 ka ago, is globally a weaker glacial. A correlation of Elster to MIS 10 implies a complicated glacial history in Europe, with various geographical areas showing evidence from different glacials. However, different chronologies of separate ice streams during the late

gives credence to such a scenario. In the Netherlands there is evidence for correlations of Elster to both MIS 12 and MIS 10. A correlation to MIS 10 is given in the comprehensive review of the glaciations of northern Germany by Litt et al. (2007)., pages 27–28. Version 2016 of the correlation table by the German Stratigraphic Commission correlates both Elster and Mindel to MIS 10.German Stratigraphic Commission: Stratigraphische Tabelle von Deutschland 2016
