Abstract

The Autochthonous Taurus 'known' petroleum system is geographically located in the eastern Taurus region and includes the Allochthonous Units and Miocene-Pliocene sequences in the Adana Basin. The total thickness of the Early Palaeozoic to Cenozoic sediments reaches 9500-10400 m. The eastern Taurus region is a major petroleum source area with three source rocks: Upper Devonian limestones, Lower Carboniferous shales and dark carbonates, and Upper Permian algal limestones and shales. The Burdigalian-Serravillian sandstones and limestones and the Late Tortonian-Messinian evaporites and shales of the Adana Basin constitute the reservoir-seal rock combinations in this petroleum system. The main periods for oil generation from these source rocks occurred during the Aptian to Bartonian, Maastrichtian and Lutetian to the present. However, the main periods for oil generation for the effective source rocks (Lower Carboniferous and Upper Permian formations) began 40 mybp and continued to 20 mybp. Oil and gas traps in this petroleum system are formed by thrusting due to Late Cretaceous and Late Eocene tectonism, strike-slip faults and unconformity surfaces. (C) 2004 Elsevier Ltd.
