Gravity method can help locate hidden structural blocks bounded by faults related to the Upper Cretaceous carbonate aquifers of Goubellat region (Northwestern Tunisia). The Quaternary deposits are present over the majority of the Goubellat plain basin and cover the Upper Cretaceous carbonate. The produced residual gravity map supported by vertical and tilt angle derivatives was used to reveal the subsurface structural framework of the study area shaped by uplifted (high gravity anomalies) and downlifted areas (low gravity anomalies). The horizontal gravity gradient and Euler deconvolution maps were elaborated in order to locate major faults. These faults are primordial for the subsurface water recharge pathways. Finally, the presented lineament/structural map is very useful for large-scale structures and lineaments mapping giving the principal keys of the preliminary structural configuration of the Goubellat Upper Cretaceous carbonate aquifers.
