A set of forty four samples from the
early Paleogene interval of Alo-1 well in
Five informal zones (A to E) were identified in this study. Zone A is the stratigraphically oldest and is characterized by the consistent occurrence of Areoligera senonensis, Areoligera coronata, Palaeocystodinium bulliforme, and Hafniasphaera septata. Characteristic of Zone B is the occurrence of Damassadinium cf. D. heterospinosum in combination with abundant Fibrocysta/Lanternosphaeridium spp., and Cordosphaeridium spp. The dinocyst assemblages in zone C are characterized by the co-occurrence of abundant Apectodinium spp., and Adnatosphaeridium spp. Zone D consists of common occurrence of Glaphyrocysta ordinata, Glaphyrocysta divaricata, Polysphaeridium subtile, Spiniferites microceras, and Adnatosphaeridium spp. Finally, Zone E is characterized by the occurrence of Homotriblium abreviatum, Homotriblium cf. H. oceanicum, and H. pallidum.
