The Avdan and Dutlu regions is an interesting province with autochthonous Geyikdağı Unit and allochthonous Bozkır Unit. At the region and its surrounding area, the autochthonous rocks is known as the Geyikdağı Unit. It starts with the bottom Late Cretaceous aged neritic carbonates (Saytepe formation) including abundant rudistes, algea and foraminifera. Pelagic fossiliferous, clayey, cherty limestone and marls (Late Cretaceous-Paleogene aged Alan formation) are seen at the more than upper parts of the autochthonous unit. There are with thin peble conglomerate-sandstone-shale-mudstone and clayey limestone at the upper of the autochthonous unit and known as Eocene flysch sequences (Beden formation). The rocks of the Geyikdağı Unit are covered tectonocially by the Bozkır Unit. Tectonic slides of the Bozkır Unit comprise the Hatip ophiolitic melange Late Cretaceous in at the bottom, and Triassic-Jurassic aged massive neritic carbonates of Gencek formation at the top.
