ABSTRACT: Palynological
study of an offshore well in the Niger delta was carried out to document the
palynomorphs assemblage and subsequently date and establish paleoclimatic
conditions in a portion of the Niger delta. One hundred and thirty seven
cutting samples provided by Chevron Nigeria Plc were composited at 27 m
interval for the study. The samples yielded forty six palynomorphs, which
include Racemonocolpites hians, Zonocostites
ramonae, Monoporites annulatus, Botryococcusbraunii, dinocyst Lycopodiumsporites spp., Pachydermitesdiederixi and Psilatricolporitescrassus. A Middle-Late
Miocene age belonging to P800 and P700 zones of Germeraad was established for
the interval studied. There were clear crests and troughs in the microfloral
abundance indicative of alternations of dry and wet climatic conditions during
the deposition of the Agbada Formation.
