Palynological Study and Age Dating of the Early Miocene Dukku Claystone Type Section of Gwandu Formation, Sokoto Basin, Northwestern Nigeria

Outcrop samples were collected from Dukku area for the purpose of subjecting them to palynological analysis in order determine relative age Gwandu Formation and palaeoenvironment deposition deposit. Field laboratory methods carried out obtain lithological sequence description outcrop. The obtained went through processes acid digestion with hydrochloric acid, hydrofluoric separation macerals by floatation use zinc bromide. prepared slides observed under microscope palynomorph contents. Diagnostic palynomorphs that are stratigraphically important palynozonation retrieved such as Belskipollis eligans, Verrutricolporites laevigatus. Striamonocolpites sp., Retibrevitricolporites obodoensis, Retistephanocolpites Cingulatisporites ornatus, Longapertites marginatus Proteacidites sp. marker fossils belong Magnatariatites horwardii zone; Zone P600 Subzone P630 C1 Nigerian Niger Delta sedimentary basin zonal schemes, dated Early Miocene age. Dinoflagellate forms recovered include Batiacasphaera Senegalinium Andalusiella polymorpha Selenophemphix nephroides, laevigata, Histrichosphaera turocona undifferentiated dinoflagellate cysts peridinacean marginal marine setting.
