Vierlandium

from Wikipedia, the free encyclopedia

Vierlandium (also Vierland stage, stratigraphic short symbol: tmiv) is the geological name for a stratigraphic unit in Northern Europe, which according to the global structure began with the beginning of Aquitanium in the Lower Mioocene (23.8 million years ago) and in Burdigalium (about 19.0 million years ago) ended. The upper limit has long been disputed. The value given here is taken from the Stratigraphic Table of Germany from 2002 (publisher: German Stratigraphic Commission). In older publications, the upper limit is usually given within the Aquitanium (around 21 million years).

The name Vierlandium goes back to early descriptions of this geological formation, which was drilled south of Hamburg (in the Vierlande area on the north bank of the Elbe). The Vierlandium includes, for example, the layers of the Klintinghoved Formation (Unterer Glimmerton) found in the German-Danish border area, the Glimmertone near Elmshorn and the Holstein rock found as local debris in outcrops in eastern Schleswig-Holstein .

Like almost all stages of the Miocene in northern Germany, the Vierlandium is also a transgressive horizon. Boreholes in the area of ​​Quickborn have shown thicknesses of up to 550 m for the Vierlandium layers, but mostly the thickness values ​​are between 10 and 50 m.
