Abstract: This study was conducted to determine, on the one hand, the granulometric and mineralogical characteristics of sediments collected from the beaches of Sassandra and Fresco, and on the other hand the factors controlling the distribution and transport of these sediments. The mineralogical procession is largely dominated by quartz and ilmenite. This procession comes from an environment of sigmoid facies consisting of medium-to-coarse sands transported mainly by saltation. Part of the mineralogical cortege in sediments would be derived from the decomposition of the metamorphic and magmatic rocks (granite, pegmatite) in hinterland and then to their coastal transport by storm water. A second part would come from the erosion of the granite of the continental shelf by tides, currents and waves. Tides, currents, waves and runoff are agents responsible for sediments distribution and transport. The concentration of identified minerals (ilmenite, quartz, zircon…) in moveable sediments provided a more or less complete picture of the distributing provinces.
