ABSTRACT A sequence biostratigraphic study of Upper Cretacerous to Tertiary sediment of part of Anambra and Niger Delta basins were carried out using sample from three exploration wells and outcrops located in the basins. Akukwa-1 1000ft 7990ft. The wells penetrated key stratigraphic units in the Anambra Basin the Nkporo Mamu Nsukka and those of the proto Niger Delta Imo and Ameki.. Akukwa yielded 21 genera and 100 species of palynomorphs The paleo-environment of deposition were determined to range from lithoral to proximal offshore in a shallow marine setting. A detailed categorization of the palynomorphs into terrestrially derived palynomorphs and marine derived palynomorphs based on the distribution of three broad vegetation type mangrove fresh water swamps and hinterland community were used to evaluate sea level fluctuations with respect to sediments deposited in the basin and linked to a particular depositional system tracts
