Late Barremian/Aptian Orbata Carbonate Platform, Central Tunisia – Sedimentary Record and High-frequency Cycles

New stratigraphic concepts such as sequence stratigraphy (Vail at al., 1977); cyclostratigraphy (Fisher, 1986; Strasser, 1994) have determinate a way of thinking which appreciates this perception. These concepts treated in detail the dynamic behavior of sedimentary systems and prove the necessity for models using cause and effect relationships and look for interdependencies mechanisms between many variables.
