描述

This study describes the palynofacies analyses carried out on 19 ditch cuttings within the depth interval of 31 – 58 m (27 m thick) from Kudu-3 well, Bida Basin Nigeria with the view to determine the palynofacies content, palynostratigraphic zonation, palaeoenvironment and paleoclimate of deposition, sedimentation rate and thermal maturity of the sediments. The studied interval consists of silty mudstone, sandy mudstone, siltstone and sandy siltstone lithologic units, indicating Enagi Siltstone. Acid methods for recovery of particulate organic matter from samples were followed. The analyses yielded low to moderate recovery of palynomorphs, small to large sizes of palynomaceral 1, 2, 3 and 4. A concurrent range zone of Verrucatosporites usmensis – Monosporites annuatus Zone, dated early Eocene is proposed for the studied interval.
