Geochemistry exploration environment analysis of waters: The case of the basin of the Great Sebkha of Oran

Abstract

Water resources are economically and environmentally the most valuable for countries affected by aridity. This study is to identify the factors influencing the quality of the waters of the aquifer system of the Great Sebkha of Oran, one area that is already in a stress situation. The determination of the origin of the salinity of the waters was approached from an analysis of the chemical type. Water mineralization is mainly governed by the phenomena of dissolution and precipitation of minerals (calcite, dolomite, anhydrite, gypsum and halite).
