Palynological Studies of Maastrichtian to Paleocene Sediments Exposed at Okpekpe, Western Flank of Anambra Basin, Edo State, Nigeria
IGBINIGIE, NS & AKENZUA-ADAMCZYK, AH
Abstract
Outcrop samples were collected at a road cut along Okpekpe road in the western part of the
Anambra Basin with a view to establishing the age of the sediments and their depositional environment. These
consist mainly of shales, sandstone, siltstone and heterolith. The samples were processed and analyzed using
standard palynological procedures. Index fossils of stratigraphic significance were used for dating of the sediments.
An extremely poor recovery of palynomorphs characterized by

was noticed.
A Maastrichtian-Paleocene age and a continental depositional environment were assigned to the sediments.
