Geochemical analyze of sediments of lake Fouarat level in Morocco reveal the existence of mineralogical associations, particularly Zn and Cu within lithochemicals substrates. The results obtained by the dosage of total metal show that the maximum contents of Zn and Cu is recorded at the station number 4. Analyze of chemical fraction shows that the Zinc was associated preferentially with iron and manganese oxides and carbonates-exchangeables cations phase. However the copper show a strong asoociation with the organic phase. The phases discussed above are easily dissociables with the slightest changes in physicochemical conditions (pH, organic matters content, ...)
