| Abstract: | The palynological analysis of the core samples from the interval 1722–1777 m of well IVCO-25, located in the Abidjan margin, has revealed a rich microflora composed of Pteridophyta and Chlorophyta spores combined with Palmaceae and Proteaceae pollen grains. This palynoflora suggests a vegetation developed under a hot and humid tropical climate, suggestive of estuarine conditions. The microplankton, composed of various species of dinocysts, were indicative of a Campanian age for the studied interval. |
