摘要:Current palynologic and stratigraphic data presented in this paper, show the existence of Upper Tertiary to Lower Quaternary deposits in the Mbere and Djerem basins. The upper part, so called “Late Continental” deposits encounters different palynomorphs with angiosperms (Gramineae, Chenopodiaceae, Malvaceae and Compositeae), spores, fungi, gymnosperm and freshwater algae, which are of Late Tertiary/Quaternary aspect. No marine palynomorph is reported. The border faults might have reworked at several occasions during post-cretaceous periods, probably during the Oligocene/Miocene as indicated by the Oligo-Miocene volcanic products associated with the “Late Continental” sedimentary series. Three periods of sedimentation can be distinguished, interbeded by erosional and volcanic phases.
