In order to gain a better understanding of the Ivorian sedimentary basin and optimize the exploitation of its resources, a number of researchers have begun work there, especially in the offshore part of the basin. However, the Turonian, having been severely eroded and presented as consisting of small thicknesses of rock, has long remained neglected. In order to fill the knowledge gap on the Turonian formations of the Abidjan margin, this study was carried out with the aim of determining the complete lithostratigraphy of the Turonian sedimentary rocks of the Abidjan margin. The work was carried out on 313 samples from five (5) wells on this margin. It involved lithological analysis and study of accessory elements (glauconites, carbonaceous debris and pyrites) using a binocular magnifying glass, as well as calcimetric study of the sediments using a Bernard calcimeter. Diagonal analysis was used to identify the lithology of the formations studied. The Turonian is characterized by dark argillites (for the most part), limestone, sands and sandstones. The sediments are essentially low in calcium carbonate. Pyrites, carbonaceous debris and abundant glauconites are found. The sediments were deposited in a shallow, semi-confined marine environment close to the mainland.

Abstract
In order to gain a better understanding of the Ivorian sedimentary basin and optimize the exploitation of its resources, a number of researchers have begun work there, especially in the offshore part of the basin. However, the Turonian, having been severely eroded and presented as consisting of small thicknesses of rock, has long remained neglected. In order to fill the knowledge gap on the Turonian formations of the Abidjan margin, this study was carried out with the aim of determining the complete lithostratigraphy of the Turonian sedimentary rocks of the Abidjan margin. The work was carried out on 313 samples from five (5) wells on this margin. It involved lithological analysis and study of accessory elements (glauconites, carbonaceous debris and pyrites) using a binocular magnifying glass, as well as calcimetric study of the sediments using a Bernard calcimeter. Diagonal analysis was used to identify the lithology of the formations studied. The Turonian is characterized by dark argillites (for the most part), limestone, sands and sandstones. The sediments are essentially low in calcium carbonate. Pyrites, carbonaceous debris and abundant glauconites are found. The sediments were deposited in a shallow, semi-confined marine environment close to the mainland.
