South German Jurassic

Lithostratigraphy of the South German Jurassic.
Abbreviations:

The term South German Jurassic (German: Süddeutscher Jura) in Earth history is used to refer to a lithostratigraphic rock unit at the hierarchical level of a supergroup. The rocks of the South German Jurassic were mainly deposited during the Jurassic period (199 to 146 million years ago). The boundaries of the South German Jurassic and those of the chronostratigraphic or international Jurassic are not, however, exactly coincident. Sediment deposition began rather later than the date of the international Triassic/Jurassic boundary and the youngest beds are Upper Jurassic in age, i.e. well before the international Jurassic/Cretaceous boundary.

The South German Jurassic is underlain by sediments of Keuper age; between them is a small stratigraphic hiatus. The upper boundary is discordant, the South German Jurassic is separated from the overlying beds by a large stratigraphic gap. In some areas it is locally succeeded by the Regensburg Green Sandstone, which is dated to the Cenomanian stage of the Cretaceous, in its southern fringes the South German Jurassic is overlain by Palaeogene molasse deposits.
