Subdivision of the Quaternary period
according to the ICS, as of 2017.[1] 'Chibanian' and 'Tarantian' are informal, unofficial names proposed to replace the also informal, unofficial 'Middle Pleistocene' and 'Upper Pleistocene' subseries/subepochs respectively.

In Europe and North America, the Holocene is subdivided into Preboreal, Boreal, Atlantic, Subboreal, and Subatlantic stages of the Blytt–Sernander time scale. There are many regional subdivisions for the Upper or Late Pleistocene; usually these represent locally recognized cold (glacial) and warm (interglacial) periods. The last glacial period ends with the cold Younger Dryas substage.

The Holstein interglacial (German: Holstein-Warmzeit or Holstein-Interglazial), also called the Mindel-Riss interglacial (Mindel-Riß-Interglazial) in the Alpine region, is the third to last major interglacial before the Holocene, the present warm period. It lasted from about 340,000 to 325,000 years ago, and is hence part of the Middle Pleistocene.

DefinitionEdit

The Holstein interglacial is defined by marine sedimentation. On the stratigraphic record at the natural monument of Sievertsche Tongrube in Hamburg-Hummelsbüttel, its development is traced from the Elster ice age (Lauenburg clay) through the start of the warm period (freshwater depositions) to its flooding by the Holstein Sea (Cardien Sands).[2][3][4][5][6]
