| The results of the lithofacies analysis of the Cenozoic section of the Cote d'Ivoire petroleum basin, based on the petrographic mineralogical analysis and particles size analysis, are outlined. According to the granulometry data, several histogram were plotted indicating the distribution of sediment grain sizes by fractions, cumulative curves, and a dynamo-genetic diagram of Rozhkov; it made possible to investigate the sedimentation conditions in the Cenozoic time. The descriptions of clastic rocks thin sections, which give valuable information about the composition and history of their formation, were also carried out in this study. As a result of the conducted study, it was established that the Fresco Formations within the Grand-Lau region was developed during the Cenozoic time in various facial conditions of the coastal-marine environment, from the shallow-water bay to littoral conditions. Keywords: lithofacies analysis, Fresco Cenozoic Formation, Cote d'Ivoire petroleum basin, Gulf of Guinea, Western Africa. |
