Palynological zonation and biostratigraphy of the nkporo formation from the akukwa-2 well, Anambra basin, Southeastern Nigeria

Biostratigraphic analysis of sedimentary sequences remains a fundamental approach for age determination, stratigraphic correlation, and palaeoenvironmental reconstruction, particularly through the study of palynomorph assemblages. The Akukwa-2 well, located within the Nkporo Formation of the Anambra Basin, southeastern Nigeria, provides valuable subsurface data for understanding the depositional history and hydrocarbon potential of the basin. A total of ten ditch cutting samples were subjecte
