Özet

The Haymana Basin in central Anatolia, Turkey, developed on a fore-are accretionary wedge during the Late Cretaceous and the Middle Eocene. Turbidite deposits hh the center of the basin and grade northwestward into shallow marine clastics and carbonates, which in turn pass into lacustrine and fluvial deposits toward the margin. The Middle Eocene Cayraz Formation represents the youngest paleotectonic unit of the Haymana Basin. It is composed of two shelf systems (SS), each formed by a package of nummulitic banks and intervening calcareous mudstones, 150-250 m thick, overlying 70-100 m thick monotonous mudstones.
