Klimaschwankungen im Pliozän von Wallensen (Hils)

A. Altehenger
Exposed in the open-work, the pliocene lignite of Wallensen (Hils, Northwest Germany) can be studied by pollen analysis on a thickness of more than 70 metres. The Pliocene epoch which in this way can be explored, may amount to some hundred thousand years. The curves of pollen frequency show long lasting oscillations owing to climatic changes during the time of formation of the lignite and suggest that these pliocene oscillations, according to their temporal rhythm,...
