Geochemical and mineralogical characterization of coastal sediments in Al-Hoceima Bay (Central Rif, Morocco)

This work aims to characterize the morphosedimentaty dynamics of shores Al-Hoceima Bay through geochemical and mineralogical analysis surface sediments. The results reveal a direct relationship between marine hydrodynamic forcing on one hand detrital inputs from land other. Calcimetric makes it possible highlight transport deposition processes at beaches bay. difference in reasonably high carbonate contents western (Isli, Cala Bonita Quemado) (> 60%) low central eastern zone (Sfiha, Souani, Salina Lharch) (≈ 15%) are mainly due influence coastal currents, littoral drift, fluvial action. higher levels heavy minerals Lharch beach (18%) expressed by volcanic outcrops Cap Quelates Jbel Tamsamen. values Souani Tayth (7% average) erosion two types NW-SE NNE-SSW, which carry sediments schist origin brought Oueds Ghiss Nekôr. In contrast, Sfiha (12%) attributed accumulation allochthonous drift carries volcanometamorphic Rass Quelates.
