Geologically Taubenberg belongs to the Molasse foothills with its characteristic east-west orientation and marks (as for example, the Hoher Peißenberg ) the northern edge of the in the Bavarian Alpine foothills and thus the geological edge of the Alps. Taubenberg is the result of debris flows of the upper freshwater molasses, which came from the south about 10-15 million years ago - when the Alps were formed. These coarse debris cones now form characteristic mountains in front of the exits of the former tertiary Alpine rivers ( , Hoher Peißenberg, Irschenberg and others). Through the ice of later glaciations they were later left as Buttes from their softer environment of fine sands and acted as icebreakers, separating the ice flows of individual glacier termini.
