The El Ghine-Oum El Khialate sebkha extends in southeast Tunisia on over than 75 km. This depression is filled by recent Quaternary deposits containing a brines aquifer situated at a depth varying from 1 to 10 m. This aquifer is highly rich in sodium sulphate. At the surface, noticeable is the deposition of mirabilite and thenardite encrusting. To quantify the salt reserves for a rational exploitation, thirty dry cores (approximately 160 m of core) were carried out in the sebkha. They underwent integrated geological, geochemical and hydrogeological studies. The estimated reserves are in the range of 8.10t: NaSO, 2.10t NaCl and 1.10t MgCl. The extraction of these salts is restricted by the relatively poor hydrodynamic characteristics of the reservoir evaluated during pumping tests. [ABSTRACT FROM AUTHOR]
