Abstract: The study region is located in the Kurveleshi belt part of the Ionian tectonic zone (Outer Albanides ). Kurveleshi belt (sub zone) is characterized by anticlinal structures with different dimensions and tectonic model with northwest to southeast direction. The Kreshpan – Verbas anticlinal structure is the northernmost structure of the Kurveleshi belt (sub zone). Based on the seismic works and drilled wells in this region, will be given some consideration of the tectonic model of this structure. The anticline structures of Kreshpan - Verbas is characterized by duplex tectonic style. The lower duplex floor is formed by carbonate and flysch deposits that build the core and limbs of the Kreshpan - Verbas anticlinal structure, which is folded before Burdigalian age. The upper floor is formed by Miocene molasses deposits that are placed transgressively on the top of lower structural floor. The hinge of the Kreshpan-Verbas anticlinal structure is eroded up to the level of Jurassic deposits. The eroded limestone of this structure have served as source rocks and has formed oil reservoir in the sandy deposits of Messinian.
