EVOLUTION AND PETROLEUM POTENTIAL OF THE IONIAN BASING (NORTHWEST GREECE) (2003)
The main orogenic movements took place at the end of the Burdigalian (IGRS-IFP, 1966). The Ionian basin evolution constitutes a good example of inversion tectonics of a basin with evaporitic base (Karakitsios, 1995): the double divergence of the basin (westwards in the central and western part and eastwards in the eastern part) is attributed to structures inherited from the Jurassic extensional phase, which were reactivated during the compressional phase as westwards and eastwards displacements respectively. In general, extensional faults were entirely transformed into either reverse or transcurrent faults and/or thrusts, which is consistent with the classical inversion tectonic scheme. Although, in some cases during the compressional phase, faults related to the extensional phase did not reactivate as thrusts in the way predicted by the classical inversion tectonics scheme, but due to the evaporitic base halokinesis, the most elevated footwalls have been thrusted over the preexisting hanging walls. This phenomenon was facilitated by diapiric movements promoted by the salt layer included in the evaporitic base of the basin. Field and available seismic data point out that, at list, a moderate detachment took place along the sub-surface evaporites.
