Stratigraphic correlations between the continental and marine Tethyan and Peri-Tethyan basins during the Late Carboniferous and the Early Permian

The compilation of detailed stratigraphic, sedimentologic and paleontologic data resulted in stratigraphic correlations of marine and continental areas outcropping today in the Tethyan and Peri-Tethyan domains: (1) the base of the Moscovian would correspond to the base of the Westphalian C in the Peri-Tethyan domain and to the base of Westphalian B in the Tethyan domain; (2) the Kasimovian, the Gzhelian and the Orenburgian would correspond in the northern Peri-Tethyan domain and Tethyan domain (Carnic Alps) respectively to the early Stephanian, the late Stephanian and the Autunian p.p. , in the southern Peri-Tethyan domain to an undifferentiated time interval. The boundary between the Stephanian and the Autunian was recognized in the Donets Basin with some doubts; (3) the Asselian, Sakmarian, Artinskian and Kungurian would correspond in all the domains to the Autunian p.p. and the Saxonian that remain difficult to separate.
