Biostratigraphic evidence of early cretaceous (Aptian – Albian) in Cote D'ivoire Sedimenatry Basin based on planktic foraminiferal data

Aptian – Albian planktonic foraminifera were studied from seven boreholes MK 1, MK 2, MK 3, MK 4, MK 5, MK 6 and MK 7 drilled in Cote d’Ivoire sedimentary basin. The latest Aptian was identified in holes by very small size planktonic assemblages represented by Hedbergella maslakovae, Hedbergella sim...

Description
Summary:Aptian – Albian planktonic foraminifera were studied from seven boreholes MK 1, MK 2, MK 3, MK 4, MK 5, MK 6 and MK 7 drilled in Cote d’Ivoire sedimentary basin. The latest Aptian was identified in holes by very small size planktonic assemblages represented by Hedbergella maslakovae, Hedbergella similis Globigerinelloides duboisi and Globigerinelloides clavatus. Albian planktonic assemblage was characterized by Ticinella primula, Ticinella roberti, Ticinella raynaudi, Ticinella madecassiana, Biticinella breggiensis, Hedbergella rischi, Hedbergella gorbachikae, Hedbergella angolae, Costellagerina lybica, Praeglobotruncana delrioensis. The presence of latest Aptian planktonic assemblages suggest that marine conditions were already established during Late Aptian - Early Albian within Côte d'Ivoire sedimentary basin during this period.Keywords: Aptian, Albian, Cote d’Ivoire, Planktonic, Foraminifera
