Abstract:

The allochthonous unit, known as Aladağ Unit or Hadim Nappe is around Aydıncık. In the area, the stratigraphic sequence starts by Asarlıkyaylası formation with Upper Devonian which made up of dolomit with macrofossil limestone, quartzite and shale. The Upper Devonian sequences are covered by Carboniferous aged Yarıcak formation, containing  alternation of fossilliferous limestone and quartzite. With Girvenella, crinoid and fusulin limestones are the representativies of the Arpalık Formation. It underlies Yarıcak formation conformably, overlied by Late Permian Kuşakdağı formation disconformably. The Kusakdağı formation starts with shale-quartzite intercalation and continues with algae limestones. Early Triassic Gökçepinar formation is made up of oolitic-stratmatolithic limestone. At the top, the Gökçepınar formation shows transition to Early-Middle Triassic Göztaşı formation with shales, marls and with bivalve limestone. Lias-Dogger terrestrial Çamiçi formation is made of red conglomerate-sandstone-mudstone, which is covered by Dogger-Malm Dedebeleni formation including varius colors of mudstone, shale, limestone with semi-terrestrial character. Stratigraphic sequence   continues with Malm-Cretaceous Cihandere formation, which is made up of dolomite and limestone. The Cihandere formation was covered by the Hasancık formation as conformable, is represented by pelagics. In the Aydıncık area the whole sequences were covered by the Burdigalian Mut formation as unconformable, is represented by neritic carbonates.
