Plio–Pleistocene sedimentation and fault segmentation in the Gulf of Corinth (Greece) controlled by inherited structural fabric

Facies, thickness and distribution of Plio–Pleistocene syntectonic deposits in the Gulf of Corinth allow us to distinguish two different sub-basins in the southwestern and southeastern margin of the graben: the Aigion Basin to the west and the Derveni Basin to the east. The boundary between the two sub-basins is a transverse, north–south-oriented structural high inherited from the compressional architecture of the Hellenic thrust belt. This structural high can be traced from the Galaxidi Peninsula (north shore) to a submerged ridge at the western boundary of the >800 m deep marine through, to an emergent anticlinal culmination of the thrust belt along the Kratis River valley (south shore). The structural high represents a lithological and mechanical barrier that has controlled fault segmentation and syntectonic sedimentation during the Plio–Pleistocene evolution of the Gulf.
