“…The northern Atlas domain of Tunisia is characterized by numerous NE-trending Atlassic folds (classically called the "Atlassic direction" in the literature) resulting from the major northwesttrending Mid-Miocene tectonic compression (Ben Ayed, 1986;Chihi, 1995;Bouaziz et al, 2002;Masrouhi et al, 2019;Khomsi et al, 2019). Although, the study area exposes sub-meridian fold belts (Fig.…”

The Cretaceous outcrops of Borj Cedria-Bou Kournine area belongs to the NE-trending Atlas system of northern Tunisia. This area exposes sub-meridian folds associated with numerous N-to NWtrending major fault systems. This study together with previous surveys reveals that this N-trending folding is believed to be related to the inversion of the Jurassic and Early Cretaceous pre-existing fault zones and generated in response to the late compressive deformations. In addition, the study area provides evidence of soft-sediment deformations by good exposures of Cretaceous-aged slump sheets. Slump folds are usually associated with several meso-scale syn-sedimentary normal faulting together with frequent reworked blocs and occasional conglomeratic horizons. All these features indicate sedimentation on irregular seafloor topography. The aim of the present study is to investigate slump folds by applying techniques to reconstruct the contemporaneous slope gradient which has triggered soft-sediment deformations. Moreover, the brittle deformation is quantified using fault kinematic analysis together with the analysis of lithostratigraphic correlation and synsedimentary structures. Considerable thickness variations of Cretaceous deposits are interpreted as controlled by normal faulting activities. Likewise, fault kinematic analysis typifies a regional pure extension that trends NNW during Barremain, NNE during Albian and probably NW during Cenomanian time. Based on slump folds analysis, the inferred sub-marine paleoslope is believed to have a northward dipping during Barremian and a NNE-dipping during Albian time. On the light of the over-mentioned interpretations, it is believed that Cretaceous sedimentation of the study area is highly controlled by major syn-depositional normal faults associated with intra basin growth faulting.These fault systems seem to be related to the Southern Tethyan expansion of the rifted continental passive margin.

“…The later compressional phase is considered to be a key factor for the establishment of the present-day NE-trending Northern Tunisia orogen (e.g. Chihi, 1995;Gharbi et al, 2015;Masrouhi et al, 2019;Khomsi et al, 2019). It is also important to note that the alpine compression is considered to be still active (Gharbi et al, 2014, Bahrouni et al, 2020.…”

“…The Mesozoic-Cenozoic petroleum potential in the Tell of Tunisia was discussed in some papers and regional works during the last years (El Euchi et al, 2004;Mejri et al, 2006;Khomsi et al, , 2019aKhomsi et al, , b and 2021. These studies account for the occurrence of potential oil/gas traps, especially in the northern offshore of Tunisia where the Meso-Cenozoic system is seemingly very interesting and potentially very prolific (Khomsi et al, 2019a, b and.…”

This special issue of the AJGS entitled Geology of North Africa and Mediterranean regions is a follow-up of the AGIC (Atlas Georesources International conferences) organized in 2017 by the Georesources Laboratory and CERTE, Tunis, University of Carthage. This event was a major occasion for geoscientists from Arabian, Maghrebian, and European countries to present their recent findings and research results in the characterization of different georesources in North Africa, the Mediterranean, and surrounding areas, thus also including the Arabian plate.This thematic issue is composed of 33 papers covering a wide spectrum of topics and fields, from architecture and thermicity of sedimentary basins to structural evolution, oil/ gas exploration, fractured reservoirs, water resources, aquifer characterization, and applied geophysics.
