Abstract
Anyama is located on the onshore of the sedimentary basin of Côte d’Ivoire. It is to the east of the basin and the formations, particularly those dating back to the Quaternary may have been studied. Based on samples, collected from two drill holes (An1 and An2), each 114 m deep, a sedimentology and mineralogy characterization of Plio-Quaternary formations was carried out. The sedimentological study was assessed by taking account the lithology, the grain size, the transport model and the environment deposit of the sediments, the morphoscopy and the exoscopy of the quartz grain. The mineralogy study was made on clays through X-Ray Diffraction (XRD). Lithological characterization, revealed the presence of clay facies (kaolinite), sandy facies and mixed sediments, all covered with the earth bar. As for the size, it indicates coarse to medium sands with a positive asymmetry to almost positive, sands moderately classified to fairly classify. The relative mineralogy reveals the presence of silicon, aluminum and iron oxides. XRD indicates that quartz and kaolinite prevail and gypsum, rutile or anatase, illite and calcium sulfate hydrate are associated minerals.
