Aptian-turonian events in central Tunisia : [pre-symposium field trip]

Abstract : The central part of Tunisia is fonned by anticlines, the axis of which are oriented SW-NE. These mountains, called Jebel, are separated by alluvial plains. The mountains consist usually of folded and faulted Aptian carbonate platform (Serdj Fm), surrounded by Albian shales and Cenomanian-Turonian marls and limestones. These lithologie contrasts controlled the landscape: massive Aptian or Turonian limestone form cliffs and ridges, while valleys and lowlands are caved in Albian-Turonian shales and marls. This pre-symposium field trip in Central Tunisia is devoted to the Upper Aptian-Turonian succession which records sedimentologic and tectonic episodes related to this peculiar period. Several noteworthy events occurred at that lime. This field trip is focused on 3 areas located between El Kef and Kasserine, close to the Algerian border.
