Pan-African Structures Evidence of Maghreb Domain (North Africa) Revealed by Aeromagnetic and Gravity Data: Special Focus on the Tunisian Territory and Surrounding Area

Pan-African structures of Maghreb (North Africa) have been studied using aeromagnetic and gravity data compilation. Special attention will be placed on the signature of these structures in the Tunisian territory and surrounding area. The comparison between magnetic analysis results and the gravity study shows a perfect agreement between the two approaches. The basement puzzle configuration and the deep-rooted fault systems have been demonstrated for the Tunisia study case. At least two Pan-African major lineaments have been revealed with different magnetic signatures: the NW–SE North Saharan Flexure and the N–S Axis. The N–S Axis can be connected to N–S mega-faults affecting the Hoggar–Tebisti Archean–Paleoproterozoic craton.
