An integrated Facie studies of an outcropping unit of the Eze-Aku Formation at the Ibii quarry site, Afikpo Basin, South Eastern Nigeria was carried out to determine the fossil assemblages of the outcrop and the lithologic variations in order to determine the age and paleoenvironment of deposition, using a total of ten samples obtained from the field. The outcrop is composed of intercalation of fine-grained siltstone and shale with varying thicknesses. The samples were subjected to Sedimentological and palynological analyses. The results for the Sedimentological analysis which involved lithologic description, lithofacies analysis and wet sieve analysis show that the samples were highly calcareous. The presence of authigenic minerals such as quartz, heavy minerals, muscovite, gypsum, and mica flakes; and a high value of shale to sand ratio, all infer a marginal marine to marine depositional environment. The palynological analysis yielded practically no palynomorph to very scanty to low quantity of palynomorphs. The palynomorphs include; Psilatricolporites SP, Laevigasporites discordatus, Diatom and Fungal spore. Although the analysis yielded no environmentally significant Palynomorph, the presence of Diatom and Fungal spore in most of the samples and the occurrence of amorphous materials infer that the outcrop was deposited in a marine setting. The age of the Formation could not be determined due to the paucity and the scantiness in the palynological assemblage.
