etude de la l'impact de lithologie sur la minéralisation

Abstract

The region of Tamanrasset is part of the Algerian Sahara is a vast arid land ,the furthest from the capital located (1970 km) from Algiers, the wadi Tamanrasset located in the Haggar This study is based on the impact of the lithology on the mineralization of the water on the sub-flux water table of Tamanrasset. The inferoflux water table is constituted of mixed ground formed by alluvium is an altered substratum coming from the fissured rock and passes progressively to the healthy rock. The study is based on a bibliographic Recherche of different studies (geological, hydrological, hydrogeological and hydrochemical) that have included this type of water reservoirs. The results of the chemical analysis of the soil extracts in the water table of the wadi of Tammanrast showed that the mineralization of the water table is closely related to the degree of alteration of the soil.
