| Abstract: | Based on palynological index species and other significant taxa, subsurface Paleozoic formation can be differentiated based on biostratigraphy. Five palynozones are recognized. One biozone is present in the Sidi Toui Formation, and indicates a middle ± upper Cambrian age. Four biozones are identified in the Ordovician, Silurian, and Permian. Permian and Triassic sediments unconformably overlie a subcrop of different Paleozoic units. Thus, a major unconformity has been identified in the south of Tunisia, which may be related to the Hercynian orogeny. |
