Abstract

The palynostratigraphy of the Nkporo Shale outcrop exposed at 84 km point along the Enugu-Umahia Express Way indicates a Late Campanian-Early Maastrichtian age. The spore-pollen/dinocysts ratio in the assemblage is suggestive of a brackish swamp (mangrove) environment of deposition. The relative abundance and dominance of marshy pteridophytes and palm pollen suggest the prevalence of humid tropical climate during the deposition of the Nkporo Shale.
