This study concerned the cuttings of two boreholes on the west margin of Abidjan. The cuttings were subjected to a chemostratigraphic analysis in order to have a clear knowledge of the composition and distribution of the chemical elements of sediments with particles less than 63µm from the Albian. It was a question of determining the different proportions of major elements and trace elements by the method of the X-Ray Fluorescence (XRF). The purpose is to define the minerals likely to be found in the sediments. Thus, it turns out that these sediments are both rich in heavy minerals and in clay minerals. These minerals could be illite, chlorite, kaolinite, potassium feldspars, mica, zircon, titanium, ritule, anatase linked to variable levels of K, Rb, Zr, Ti, Al, Ga and Mg. the variation in the elements shows the presence of two sources, provenance of sediment. The first source is rich in heavy elements and the second in potassium and magnesium. The characteristics of these sediments show the presence of a transgression phenomenon on the passage from sequence 1 to sequence 2.
Author Keywords: Chemostratigraphy, trace elements, heavy elements, deposit environment, source/origin.

Abstract: (french)
Cette étude a concerné les déblais de deux forages de la marge Ouest d’Abidjan. Les déblais ont fait l’objet d’une analyse chimiostratigraphique en vue d’avoir une nette connaissance de la composition et de la répartition des éléments chimiques des sédiments de particule inférieur à 63 µm de l’Albien. Il a été question de déterminer les différentes proportions des éléments majeurs et des éléments traces par la méthode du Spectromètre à Fluorescence X (SFX ou XRF en anglais). Le but est de définir les minéraux susceptibles de se trouver dans les sédiments. Ainsi, il en ressort que ces sédiments sont à la fois riches en minéraux lourds qu’en minéraux argileux. Ces minéraux pourraient être l’illite, la chlorite, la kaolinite, les feldspaths potassiques, le mica, le zircon, le titane, le rutile, l’anatase liés à des taux variables de K, Rb, Zr, Ti, Al, Ga et Mg. La variation des éléments montre la présence de deux sources/provenance des sédiments. La première source est riche en éléments lourds et la deuxième en potassium et en magnésium. Les caractéristiques de ces sédiments montrent la présence d’un phénomène de transgression au passage de la séquence 1 à la séquence 2.
