Abstract
Northeast of Tunisia is part of the Maghrebides orogenic belt characterized by a complex geology. The geodynamic of this area has long been challenging because of the deficiency of seismic and geological data. In this respect, we intend to use gravity land data to understand the subsurface geology of the study area. The gravity assessment of the complete Bouguer gravity anomaly is mainly based on the use of many filters applied to decipher fault patterns by enhancing near structures and approximating edges of the sources bodies on the one hand, and to estimate the burial depths of delineated structures on the other hand. The compilation of the detailed gravity analysis confronted to geological data and well data helps clarify the structural distribution in the study area. Our compiled maps reveal the presence of several gravity lineaments and some structures that are well-known surface geology as well as buried structures with different geometries not expressed by surface geology. Results from a regional NNW compressive, the updated structural pattern is conformal to the classic analogical Riedel model of which the interference of both extensive and compressive geologic elements is highlighted. The proposed structural architecture is controlled by E–W major rooted faults, which are linked to a regional EW transcurrent shear zone induced by the African and European plate convergence.
