TLDR
In this paper, structural interpretation of surface and subsurface data in the Eastern foreland basins of Tunisia, allows us to recognize positive inversion structures, i.e. related to compressional events, expressed and recorded in the Paleogene sedimentary pile of the Atlas domain.About:

Journal ArticleDOI
The southernmost margin of the Tethys realm during the Mesozoic and Cenozoic: Initial geometry and timing of the inversion processes
Dominique Frizon de Lamotte,Camille Raulin,Nicolas Mouchot,Jean-Christophe Wrobel-Daveau,Christian Blanpied,Jean-Claude Ringenbach +5 more
TL;DR: The existence of synchronous geodynamic events from one end of the system to the other, although they do not have the same meaning, is emphasized in this article, where two of them are particularly important: the Campanian-Santonian (C-S) event corresponds to obduction and exhumation of high pressure-low-temperature metamorphic rocks around the Arabian promontory, inversion along the margins of the East Mediterranean basins, and lithosphere buckling in the Atlas system (Maghreb and adjacent Sahara platform).

Late Triassic-early Jurassic block tilting along E-W faults, in southern Tunisia: New interpretation of the Tebaga of Medenine
Camille Raulin,Dominique Frizon de Lamotte,Samir Bouaziz,Sami Khomsi,Nicolas Mouchot,Geoffrey Ruiz,François Guillocheau +6 more
TL;DR: The Tebaga of Medenine is interpreted as resulting from large scale block tilting, mainly controlled by inherited E-W major faults, the Azizia fault system.
Journal ArticleDOI
The Late Eocene and Late Miocene fronts of the Atlas Belt in eastern Maghreb: integration in the geodynamic evolution of the Mediterranean Domain
TL;DR: In this paper, structural cross sections depict that the Late Eocene front of the Atlas Belt extends far through the Northern Africa plate margin comparatively to the Late Miocene front cropping out in the Eastern Tunisian Atlas.
Journal ArticleDOI
Structure, paleogeographic inheritance, and deformation history of the southern Atlas foreland fold and thrust belt of Tunisia
TL;DR: In this article, the role of the Late Triassic-Early Jurassic rifting inheritance in the structuring of the active foreland fold and thrust belt of the southern Tunisian Atlas, in particular in the development of NW-SE oblique structures such as the Gafsa fault, was confirmed.
Journal ArticleDOI
Style of Atlassic tectonic deformation and geodynamic evolution of the southern Tethyan margin, Tunisia
TL;DR: In this article, the structure of the southern Atlas fold-and-thrust belt of Tunisia was investigated using new geologic mapping, seismic reflection data together with the construction of a balanced cross section.

The two main steps of the Atlas building and geodynamics of the western Mediterranean
TL;DR: The Atlas system (Morocco, Algeria, and Tunisia) constitutes an important morphologic barrier fringing the Sahara platform as mentioned in this paper and its structural style changes along strike from a thick-skinned style in Morocco to a thin-skinned one in Algeria and Tunisia.

The circum-Mediterranean anorogenic Cenozoic igneous province
Michele Lustrino,Marjorie Wilson +1 more
TL;DR: In this article, a comprehensive review of published and new major and trace element and Sr-Nd-Pb isotopic data (more than 7800 samples) for the magmatic rocks, a common sub-lithospheric mantle source component is identified for most of the region.

Tectonic evolution of the northern African margin in Tunisia from paleostress data and sedimentary record
TL;DR: In this paper, a reconstruction of the tectonic evolution of the northern African margin in Tunisia since the Late Permian combining paleostress, stratigraphic and sedimentary approaches allows the characterization of several major periods corresponding to consistent stress patterns.
Journal ArticleDOI
The Western Mediterranean basin geological evolution
TL;DR: In this article, the Western Mediterranean Sea is explained as a marginal basin, generated by a N-NW subduction of the African-Apulian plates beneath the European plate.

Mesozoic and Cenozoic vertical movements in the Atlas system (Algeria, Morocco, Tunisia): An overview
Dominique Frizon de Lamotte,Pascale Leturmy,Yves Missenard,Sami Khomsi,Geoffrey Ruiz,Omar Saddiqi,François Guillocheau,André Michard +7 more
TL;DR: In this paper, the authors analyse the origin of these striking contrasts in relation with i) the Variscan heritage; ii) crustal vertical movements during the Mesozoic; iii) crust shortening during the Cenozoic and finally, the occurrence of a Miocene-Quaternary hot mantle anomaly in the west.
