Permocarbon

Permo-Carboniferous is a collective term for continental, often molassoide sedimentary rock successions whose older layers during the younger Carboniferous and their younger layers during the earlier Permian came to deposit. One of the reasons for the summary is that within such a sequence the boundary between the Carboniferous and Permian layers can often only be determined relatively vaguely due to the lack of chronostratigraphically indicative fossils (see → key fossil ).

In the German-speaking area, the term Permosiles (ium) is also in use for such strata sequences , after the term Silesium for the Upper Carboniferous Central Europe, which at least in the higher part ( Westfalium and Stefanium ) is consistently continental to marginal marine ( paralis ). The “Permian” part of these sequences is delineated on a lithological basis as Rotliegend , whereby the base of the Rotliegend is still in the uppermost carbon.

On the surface there are sequences of permocarbons in Germany in the Saar-Nahe valley , in the Thuringian Forest and in the Vorerzgebirgs valley .
