Apport de la méthode gravimétrique couplée avec la méthode de la sismique réflexion 2D à l’étude des structures géologiques salifères en subsurface de la plaine d’El Aroussa (Nord-Ouest de la Tunisie). Implications structurales et hydrogéologiques

Abstract

The geological understanding of subsurface geological structures and the dynamics of water transfer and storage in carbonate and silico-clastic aquifers is a very open field of research, which can bring important elements to the management of water resources.This work is focused on the application of geophysical methods (2D seismic reflection and gravimetry), for the geological and geophysical characterization of saline structures buried in the subsurface of the plain of El Aroussa (North-West of Tunisia) and their impact on the quality of water housed in aquifer geological formations.The results of the geophysical (quantitative and qualitative) gravimetric data analyzes made it possible to highlight the subsurface structural architecture of the geological structures at different depths at the level of the study area Aquifères carbonatés, Silico-clastiques, Sismique réflexion 2D, Gravimétrie, El Aroussa (Nord-Ouest de la Tunisie).
