Abstract

Hamma Bouziane Basin is the lowest point of the hydrogeological system in Constantine area. It is characterized by a plain topography (elevation between 450et550 m) and by the presence of a carbonate substratum (neritic) very karstified which are associated with ancient thermal events   (development of quaternary travertine limestone).

lithostratigraphic column, shows the succession of two stratigraphic units: Cretaceous  neritic substratum and Plio- Quaternary blankets .

Detailed mapping of Quaternary and active faults as well as tectonic measurements indicate that normal faulting has been the dominant tectonic regime north of Constantine region during quaternary phases .

Morphostructural map established from aerial photos shoes  that this basin delimited by  N30° striking   faults ,is a section of the paleogeographic faults boundary of Constantine plateforme .This structure with probably Cretaceous heritage (Dj Bergli) was remobilized during the Plio -Quaternaire as normal fault.
