| Popis: | In order to assess the relationship between the groundwater mineralization of Roc-Blanc watershed (Morocco), lithology, fracturation and abandoned mine tailings in the area, a multidisciplinary work was conducted by using the geochemical assessment approaches. Geological and hydrochemical results showed the following: (i) the main direction of fractures and the groundwater flow investigations reveal hydrogeological structures as dividing axis according to the SE and NW directions; (ii) correlations between the principal elements (Cl−, SO42−; Na+, Cl−) indicate that the mineralization of the Roc-Blanc groundwater is deduced from sulphates, chlorides and alkaline formations and iii) the dissolution of carbonate, gypsum and anhydrite constitutes the principal source of the mineralization processes. The saturation index shows that dissolution of gypsum and anhydrite is one of the origins of sulphates and calcium in the water resources of the study area. Abandoned mine tailings have no effects on the groundwater quality. |
