We present several structural transects throughout the internal part of the Tunisian Tell focusing on some representative structures and domains. We used also an interpreted seismic cross-section and a 3-D structural view to highlight the styles within the Tellian units in the Fernana-Adissa allochthon domain. The structural style is mainly represented by active roof-thrust and duplex structures affecting the Mesozoic-Cenozoic sequences belonging respectively to the infra-Kasseb and Kasseb units. The main decollement thrusting layer is located in the Triassic evaporites, while the roof thrust corresponds to the Upper Cretaceous or to the Paleocene shaly levels. The structural transects allow viewing that the Numidian Flysch unit presents different structural configurations and relationships with its subsurface supporting units; (1) it rests on an apparent stratigraphic contact above the underlying Kasseb nappe or even over pre-existing Triassic salt structures while elsewhere (2) it is detached above these infra-Numidian units reworking an originally downlap contact. The area is also characterized by important halokinetic movements controlling the overall architecture of the Tell fold-and-thrust belt that allows the thrusting of the whole Tellian wedge. In addition, originally apical parts of former diapiric structures were remobilized subsequently as sole thrust allowing the displacement of the Numidian Flysch. The Upper Miocene syn-folding sequences sourced by the erosion of the precedent uplifted reliefs are folded and tectonically transported along some active thrusts by the Tell tectonic units suggesting a recent reactivation and rejuvenation of thrust during the Upper Miocene to Quaternary Alpine events. Since the Late Miocene, shortening is still active today, allowing the refolding of older nappes contacts as well as rejuvenation of inherited faults.

我们在突尼斯泰尔的内部展示了几个结构断面，重点是一些有代表性的结构和领域。我们还使用解释过的地震横截面和 3-D 结构视图来突出 Fernana-Adissa 异地域中 Tellian 单元内的样式。构造样式主要以影响中新生代层序的活动顶逆冲构造和复式构造为代表，分别属于下卡塞布单元和卡塞布单元。主要的滑脱冲断层位于三叠纪蒸发岩中，顶板冲断层对应于上白垩统或古新世页岩层。结构断面允许观察 Numidian Flysch 单元呈现不同的结构配置以及与其地下支撑单元的关系；(1) 它位于下伏 Kasseb 推覆之上的明显地层接触上，甚至位于先前存在的三叠纪盐结构之上，而在其他地方 (2) 它在这些 Numidian 下单元上方分离，重新加工了最初的下重叠接触。该地区的另一个特点是重要的盐动力运动控制了泰尔褶皱和逆冲带的整体结构，允许整个泰利安楔形推力。此外，前底辟结构的最初顶端部分随后作为唯一的推力重新活动，允许 Numidian Flysch 位移。上中新世同褶皱序列源自先行的隆起地貌的侵蚀，被泰尔构造单元沿一些活跃的逆冲推力折叠并在构造上运输，这表明在上中新世至第四纪高山事件期间逆冲推力最近重新激活和恢复活力。自晚中新世以来，今天的缩短仍然活跃，允许旧推拿接触的重新折叠以及继承断层的恢复。
