Abstract: The palynological analysis and paelodepositional environment of the Ajaka area were analysed using a detailed study of outcrops and a borehole section. Results show that two major lithostratigraphic units outcrop in the area; dominantly conglomerate unit which can be subdivided into the paraconglomerate and the orthoconglomerate subunits, and the massive sandstone unit. The massive sandstone facies consists of fine-to-coarse grained massive sandstone. The sand grains are angular to subrounded and poorly to moderately sorted. This facies is interpreted to have formed as a result of transport and deposition by short-lived mass flows. The palynological analysis, indicate the presence of Retidiporites miniporatus, Hexaporotricolpites emelianova and Buttinia andreevi, which all are indicative of the Maastrichtian age bracket in the geological time scale. This evidence thus suggests that the outcrops of Ajaka and environs are Maastrichtian in age.
