Evidence of Campanian-Maastrichian palynomorphs from Lamja Formation, Yola Sub-basin, Northern Benue Trough, Nigeria
Sarki Yandoka, B.M

ABSTRACT
The Lamja Formation marks the end of sedimentation in the Yola Sub-basin of the Northern Benue Trough. The formation was assigned to the Upper Santonian age. However, recent palynological studies of samples from Lamja Formation recovered Campanian-Maastrichian palynomorphs that include the following palynomorphs species; Monoporites annulatus, Logapertites marginatus, Proteacidites sigalli, Monocolpites marginatus. This shows that there is a possibility of sedimentary deposition in the Yola Sub-basin immediately after the mid-Santonian tectonic inversion. However, the CampanianMaastrichian palynomorphs species recovered in this study are similar and can be correlatable to other Cretaceous palynologic zones in the West Africa and South American basins
