Abstract

In south-eastern Turkey, a transgressive phase with a rich benthic foraminiferal association followed the Late Cretaceous emplacement of nappes onto the passive northern margin of the Arabian Platform. At the base, this transgressive sequence is represented by coarse clastics and local carbonate intercalations of the Antak Formation and the overlying, shallow water friable sands and carbonate facies of the Besni Formation, which is characterized by a sudden proliferation of benthic foraminifera, rudists and other macrofossil groups. Finally, below the unconformable Tertiary units, the more basinal marls and regressive sandstone--carbonate lithologies of the Germav Formation complete the Mesozoic succession.
