Abstract
The sedimentary basin of Côte d'Ivoire has generated numerous geophysical, sedimentological and biostratigraphic research. However, the lithostratigraphic characteristics for revealing seismic processes are very little known. This study was carried out with the aim of understanding the relationship between sea level variations and seismic terminations. the studies carried out relate to the lithostratigraphic analysis of two seismic profiles of Senonian age in the Abidjan margin. The seismic study of this work is based on the interpretation of the seismic profile. Recognizing reflector terminations and reflector geometries is arguably one of the most useful aspects of this approach. the seismic profiles show the Senonian formation is generally continuous and of approximately constant thickness overall. overall, the formation is affected by simple normal faults offshore, note the presence of structures that could constitute structural hydrocarbon traps.
