Stratigraphic Table of Germany 2002 (STG 2002)

STG 2002

The Stratigraphic Table of Germany 2002 of the German Stratigraphic Commission has been created on the occasion of the german “Year of Geosciences 2002” by 88 authors from 38 institutions. Its global stratigraphic reference scale shows the stratigraphic terms of the International Commission on Stratigraphy (2002).

Due to create a consistent time scale without streched and compressed time spans the error bars of the isotopic ages has been used. For example, the U-Pb IDTIMS ages from the Upper Devonian were made as young as possible and the U-Pb SHRIMP ages from the Mississippian were made as old as possible. Thus, the error rectangels of the isotopic ages which are defined by the analytical and the stratigraphical error are all cut by the time line. For instances, the resulting ages, rounded to full millions, are 358 (362-354) Ma for the Devonian-Carboniferous boundary, 296 (299-292) Ma for the Carboniferous-Permian boundary and 251 (253-250) Ma for the Permian-Triassic boundary.

The Devonian to Triassic stages of the global reference scale were integrated calibrated using isotopic ages and numerous geological time indicators. Thus, their duration is between ca 19 Ma (Visean) and ca 2 Ma (Indusian). The Mississippian is significant longer than the Pennsylvanian, the Lower Permian (Cisuralian) is as long as the sum of Middle (Guadalupian) and Upper (Lopingian) Permian, the Upper Triassic is longer than the sum of Lower and Middle Triassic.

The Rotliegend group begins in the uppermost Carboniferous Gzhelian stage and reaches up the Upper Permian. Therefore, Rotliegend can not be longer named as „Lower Permian“ but as Lower Dyas.

The lithofacies of the Central European sections is differentiated by colours. In the Carboniferous the uppermost full marin sediments, the Hangende Alaunschiefer, reach up to the Kinderscoutian. During the following ca. 7,5 Ma (paralic facies) there are several ingressions up to the lowermost Westfalian C (Bolsovian). However, during the next ca 53 Ma up to the uppermost Rotliegend no marine ingression took place. The continous full continental facies is the main reason for the tremendous correlation problems in the upper Westfalian, Stephan(ian), and Rotliegend. Such a long time span without any marine mark but with numerous large gaps of unknown duration never occured in Central Europe before or later during the Phanerozoic. To elucidate inaccurate ages and correlations numerous arrows with question marks are shown within the table.
