Abstract: | Major ion geochemistry, Chadha diagram, saturation indexes, correlations between physico-chemical parameters and hydrochemistry evolution; were used to identify the origins and processes of groundwater mineralization in multilayer system aquifers in the southern part of the of chotts region mining district (Algerian-Tunisian border). The results suggest that the shallow groundwater in the study area are mineralized salt waters. More than 91% of samples characterized by water type Ca-Mg-SO4/Cl, and the other samples are characterized by water type Na_Cl. As illustrated by the Chadha diagram. The relationships between TDS and major ions are useful for interpreting the main hydro geochemical evolution processes in an aquifer. For cations, there is a good correlation between Na⁺ and TDS (R²=0.67), and the correlation of Ca²⁺ and Mg²⁺ with TDS is good, with R²= 0.30 and R²= 0.5, respectively. For anions, SO₄²⁻ and TDS have the highest correlation R²=0.5 followed by the correlation between Cl⁻ and TDS (R²= 0.4).... |
