Abstract

Sedimentary rocks cuttings from two boreholes in Bingerville and Assinie (Côte d’Ivoire) were the subject of this study.

Sands and clays were collected from the Bingerville well and sands, green clays and limestones from the Assinie well.

The main objective of this work is to make an inventory of the plant species that existed at the time of the deposition of sediments on both sides of the lagoon fault based on palynomorph fossils.

Paleovegetation consisted of freshwater species such as (determined spores Verrucatosporites usmensis, Laevigatosporites ovatus,Polypodiaceiosporites regularis,and Deltoidospora delicata), which thrieved in a coastal wetland environment under a tropical climate with alternating warm and humid periods. Palynostratigraphic analyzses point to the age of the Upper Eocene and the Lower Miocene for the studied samples.

Keywords:
Palynomorphs, paleovegetation, miocene, eocene, Bingerville, Assinie.
