Observations palynologiques dans le Couvinien (Emsien terminal et Eifelien) du bord oriental du synclinorium de Dinant, Belgique

The Couvinian (a chronostratigraphical unit equivalent to the Uppermost Emsian and to the Eifelian) was made the object of palynological studies concentrating as much on acritarchs as on spores in the eastern flank at the synclinorium of Dinant. The samples are located in a lithological sequence, certain of the units in which are new and defined here for the first time. Their biostratigraphical relations with the type sequence on the south side of the basin were established on the bases of brachiopods. Twenty-three spore species are recorded. Grandispora velata and hystricospores make their fi... Mehr ...
