Palynological study of 50 ditch samples from a segment of GBO-04 well located onshore western Niger Delta Basin was carried out determine the age of the sediment and reconstruct the paleoclimate and paleodepositional environments. All the analyzed samples were composited at 60 ft. from stratigraphic depth interval of 3010 to 6030 ft. The lithology was made of shale and friable sandstone. Palynological slides were prepared following standard palynological preparation procedure involving sample maceration with hydrochloric (HCl) and hydrofluoric (HF) acids. The samples yielded well preserved, moderately diversified palynomorph assemblages comprising 72 taxa and belonging to pollen, spores, dinoflagellates, acritarch, algae and fungi spores. The stratigraphic distribution of floristic assemblage was highly variable. The assemblage was dominated by pollen and spores. The pollen included .. View More»
