New Insights on the Marine to Non-marine Oligo-Miocene Deposits of Northern Tunisia: Sedimentary Events and Paleogeography

Abstract

The gathering of new biostratigraphic results together with those already updated and collected from previous works on the Oligo-Miocene deposits of the Bejaoua and Fortuna groups from northern Tunisia allow the establishment of an accurate regional litho-biostratigraphic framework. Furthermore, the compilation of faunal assemblages and sedimentary facies enabled the precision of the spatiotemporal relationships between the marine and non-marine sedimentary events that recorded during this time interval and also the update of three key time interval paleogeographic maps. These illustrate the major transgressive and regressive sedimentary events recorded in the southern Tethyan realm of Tunisia during the Oligo-Miocene time interval.
