Abstract
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 , P raeglobotruncana delrioensis . The presence of latest Aptian planktonic assemblages suggest that marine conditions were already established during Late Aptian - Early Albian within Cote d'Ivoire sedimentary basin during this period. Keywords: Aptian, Albian, Cote d’Ivoire, Planktonic, Foraminifera
