Danube-Günz interglacial

from Wikipedia, the free encyclopedia

The Danube-Günz interglacial (also Danube-Günz warm period , Danube-Günz or Uhlenberg warm period for short ) is the second-oldest named warm period of the Pleistocene of the Alps . It lies between the Danube and Günz Glaciers .

structure

The Danube-Günz interglacial is defined as the erosion phase that follows the Danube glacial period and preceded the Günz glacial period. It is therefore represented by the gap between the deposits, which are ascribed to the two glacial periods; in the type regions of the two glacial periods, these are different deposits. In the area of ​​the Iller-Lech-Platte it lies between the lower deck gravel of the Zusam -Platte and the intermediate gravel , in the area of ​​the Salzach Glacier between the Eichwald gravel and the Elder Top gravel and in the area of Traun and Enns between the Prägünz gravel and the older ones Ceiling gravel . The erosion phase associated with the interglacial is very pronounced, and the composition of the gravel in the area east of the Rhine Glacier changes significantly.

Biostratigraphically , the interglacial in the so-called Uhlenberg profile was dated pollen stratigraphically . The assignment to MIS 23 or 25 is uncertain, so an age of approximately 900,000 to 940,000 years would result. However, there are indications that the Uhlenberg profile can still be placed in the Pliocene and thus could not be correlated with the Danube-Günz interglacial. The assignment to the North German division is also uncertain; due to its position in the lying area of the Günz, it could correspond to the Bavelium or the Waal interglacial .

The Danube-Günz interglacial corresponds at least partially to the Swiss gravel glaciations.
