Lower Albian Sequence Stratigraphy of the South Tethyan Margin: The Tajerouine Area, Tunisia
Central Tunisia, part of the South-Tethyan passive margin, is marked by the transition from the southern stable Sahara platform, to the open marine Tethyan basin and to the North. Detailed biostratigraphic and sedimentological studies of the Early Albian succession in the El Kef-Tajerouine area allowed us to define five depositional sequences which are well correlated in Central Tunisia. They give evidence of the drowning of the Aptian-earliest Albian platforms and the diachronic SE-ward back-stepping of the shelf facies. Tectonic synsedimentary deformation began in the earliest Albian, increased in intensity throughout the Early Albian and culminated with the Middle Albian sedimentary hiatus.
