Abstract
2D-seismic reflection profiles and borehole data, in the studied area of approximately 18,850 Km2 and reaching depths between 1200 and 4000 m, have been investigated to characterize the Southeastern Tunisia during the Paleozoic period. This study aims to enhance the geologic understing of the area by analysing the Paleozoic distribution. Three main unconformities were indentified in this area: unconformity A, between the Ordovician and Silurian series (Probably the Taconic unconformity); unconformity B, between the Silurian and Triassic series resulting from the Hercyninian Orogeney; and unconformity C, separating the Permian from Triassic deposits. The seismic interpretation has confirmed the existence of several features dominated by NW–SE trends associated with horst and graben structures. These tectonic elements have an important role in the structural and stratigraphic traps.
