Abstract
In the Mediterranean Sea, the Cenozoic corresponds to a compressive period represented by folding phases and basin filling. The Tertiary structural development of North Eastern Tunisia is characterized by two tectonic phases: the Oligo-Miocene rifting and the late Miocene compression. These tectonic events came along with global eustatic and climatic changes. In order to identify the response of the Miocene sedimentary deposits in north-eastern Tunisia to global events, five wells from the Gulf of Hammamet and three outcrops from the surrounding area, were studied. A multidisciplinary approach integrating biostratigraphy, facies analysis, interpretation of depositional environments, and structural setting has been adopted. Thus, three transgressive events were recognised during the lower to middle Miocene, and an eustatic fall is identified in the early Serravalian–late Langhian.
