Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Mechanical relationship between strike-slip faulting and salt tectonics in the Northern Tunisian Atlas: The Bir-El-Afou salt structure

“…An Atlantic-type passive margin salt tectonics was also identified from Jerissa to Nebeur area (Jaillard et al, 2017). Recently, an interconnected salt diapir-allochthonous salt sheet was moreover recognized in the Lansarine-Baouala structure (Amri et al, 2020). In this paper, we present, for the first time, a salt structure associated with strike-slip fault systems in Northeastern Maghreb Salt Province (Fig.…”

“…Vila et al, 1996;Ghanmi et al, 2001;Slama et al, 2009;Masrouhi and Koyi, 2012). This study is part of a structural revision where we compare data from salt structures in Tunisia with well-documented salt-tectonic systems in the Northeastern Maghreb salt province and other halokinetic systems (e.g., Masrouhi et al, 2013;Masrouhi et al, 2014a;Amri et al, 2020).…”

“…It was responsible for the configuration of Triassic basin largely filled with evaporitic deposits across major parts of Tunisia (Kamoun et al, 2001;Soussi et al, 2017). During Jurassic to early Cretaceous, a major extensional event correlated to the opening of Central Atlantic Ocean prevailed (Soussi et al, 2000;Boughdiri et al, 2007;Bahrouni et al, 2016) and was accompanied in some locations in northern Tunisia with volcanic and halokinetic activities (Mattoussi Kort et al, 2009;Jaillard et al, 2017;Amri et al, 2020). Moreover, early to middle Albian seems to coincide with the final stage of the Atlantic Ocean opening (Jaillard et al, 2013).…”

South Tethyan passive margin paleoslope orientation inferred from soft-sediment deformation and fault kinematic analysis: a case study from the Cretaceous of Borj Cedria area, Tunisia

“…Moreover, during the same period, relevant Cretaceous halokinesis indicated thick and/or thinskinned tectonic extension (Slama et al, 2009;Masrouhi and Koyi, 2012;Amri et al, 2020). The early to middle Albian is perceived to coincide with the final stage of Atlantic Ocean opening (Jaillard et al, 2013a, b).…”

“…These particular features (both halokinetic and volcanic activities) characterize the Tethyan passive margin style (Mattoussi Kort et al, 2009;Dhahri andBoukadi, 2017, Jaillard et al, 2017). In addition, the late Aptian to the lower-middle Albian period is characterized by the most extensional event of the south Tethyan margin in northern Tunisia (Souquet et al, 1997;Masrouhi et al, 2014b, Naji et al, 2018aAmri et al, 2020). A paleogeographic differentiation between platforms in central and southern areas (Gharbi et al, 2013) and a deep trough in the northern area is implied (Burolet, 1956).…”
