Danube (geology)

Source: Wikipedia, the free encyclopedia.

Danube or Donau is a timespan in the glacial history of the Alps. Danube is currently regarded to have started approximately 1.8 million years ago, at the start of the Calabrian age of the international geochronology. It ended approximately one million years ago. Deep sea core samples have identified approximately 20 glacial cycles during Danube.[1]

History of the term

The Danube glaciation, Donau glaciation (

Danube-Günz interglacial
.

The 2016 version of the detailed stratigraphic table by the German Stratigraphic Commission firmly places Danube (Donau) in the

Menapian, and perhaps Bavelian in the glacial history of Northern Europe.[1]

Glacial cycles

Deep sea core samples have identified approximately 40

marine isotope stages (starting with MIS 63 and going no further than MIS 20).[1] Thus, there have probably been about 20 glacial cycles of varying intensity during Danube. The dominant trigger is believed to be the 41 000 year Milankovitch cycles of axial tilt, but the Mid-Pleistocene Transition to 100,000 year cycles starts towards the end of Danube.[4][5]
