The detalied analysis of textural features like the grain size distribution with Folk and Ward indicators, rounding and frosting of quartz grains and mineral composition of the beach and aeolian sediments of Fuerteventura Island were undergone. Not only variety, but also commonly features allow to conclude about environmental conditions while depositing. The mineral composition of both beach and aeolian deposits is strongly controlled by the geological structure of the island. Beach deposits are characterized by enrichment in partially rounded frosted quartz grains (EM/RM) instead of typical beach-like grains (EL and EM/EL). It might be caused by strong influence of Saharan Air Layer (Calima). Aeolian deposits are slightly transformed by wind in comparision with the beach deposits. They build, however significant forms.
