Context: All the research is focused on understanding the functioningof the southeast onshore basin. However, research on the southwestern part is not very developed. It is to compensate for this lack of interest in this area that this study is conducted. Objective: To describe the morphological nature and sedimentary dynamics of the deposits crossed by two boreholes. Method: It is based on the study of 156 samples of drill cuttings analyzed lithologically, calcimetrically, morphoscopically and granulometrically. Results: It revealed a sedimentation dominated by clay, marked by a frequent presence of carbonaceous debris, pyrite and glauconite indicating a shallow marine reductive deposit environment. Calcimetric analysis revealed two levels: a first level with zero calcium carbonate content reflecting an agitated environment and coinciding with detrital deposits and a second with high carbonate content (40%) explaining a calm depositional environment. The morphoscopic study of the quartz grains allowing to describe the different environments of evolution of the sediments before their immobilization has highlighted three types of grains. Sub-angular and sub-rounded grains with a blunt shiny appearance (61%) resulting from fluvial transport and round-mât grains (28.5%), transported by the wind. Unworn grains represent about 10%. The presence of these grains indicates a nearby source of supply, with little reworked sediment. Grain size analysis revealed medium to very coarse grains, fairly well to poorly graded asymmetrically towards fine elements reflecting an environment with variable hydrodynamics ranging from strong to medium. The frequency curves and modes showed sigmoidal and polymodal modes reflecting the origin of sediments from several sources in a depositional environment with a particularly strong hydrodynamic regime. Conclusion: This study has led to a better understanding of the origin the material and the hydrodynamic conditions of the sediments in this onshore part the Ivorian sedimentary basin.
Keywords: hydrodynamics, sedimentary basin, particle size distribution, depositional environment.
