dc.description.abstract | The analyzed materials obtained by editorial preparation of a new map series, scale 1 : 1 000 000, and generalization of earlier data show that, contrary to prevailing opinions, the Middle to Upper Carboniferous deposits bearing fossil floras, pollen assemblages, brachiopods, and bivalve molluscs of marine, brackish-water, and fresh-water origin are widespread in the eastern Tunguska syneclise. On the contrary, Lower Permian deposits are of extremely limited distribution here and, occuring in the southeast only, they completely wedge out to the northwest. Rare finds of foraminifers, similar to Early Permian arctic forms, do not indicate the Early Permian age of deposits (it would be contradicting data on all other groups of fossils), but suggest presence of facies similar to those, which are peculiar of the Upper Permian in the Arctic basin. Large-leaved cordaitanthaleans most typical of the early Permian occur in association not only with Late (Alykaevo) but also with Middle Carboniferous (Mazurovo) plant assemblages that testifies to their earlier origin than in Kuzbass. | |
