ABSTRACT: The study of the tectono-sedimentary
evolution of the lower Cretaceous series realized in the southern on the
tethysian margin in the Tunisian central-Southerner Atlas, shows that the
architecture of this field is governed by a NW-SE compressive phase. This
latter has reactivated the old faults to give birth to associated, distensive
and compressive structures at the same time simultaneously. It is about a
network of combined strike slip fault EW dextral and sinistral NS which divided
the cover into four zones of deformation corresponding to the right dihedron of
the strike slip fault system. In the compressive dihedron, the deformation develops
essentially several folds and in the distensive dihedron, normal faults which
delimit horsts and grabens.
