Abstract

The interpretation of 3,500 km of high-resolution seismic reflection profiles revealed that the tectonic evolution of the Finike Basin and its immediate surroundings involves three phases of deformation since the Miocene. A protracted contractional phase dominated by southwest-northeast trending fold-thrust structures ocurred during the Early-Middle Miocene. This phase culminated during the Messinian, and was replaced by an interval of relative tectonic quiescence. The transition from the latest Miocene to Pliocene-Quaternary was marked by a reactivated tectonism. This phase was dominated by partitioned strain, including: (i) reactivation and northwest-southeast directed contraction in the Finike Basin extending into the southern Turkish continental margin, (ii) extension and transtension along the westernmost Antalya Basin and the adjacent continental margin, and (iii) contraction and transpression across the The Sırrı Erinç Plateau and the northern slopes of the Anaxagoras Mountain. A tectonic model is proposed where the development of these diverse tectonic regions can be explained by the development and temporal evolution of the intracontinental Beydağları Block, which experienced a 20º counterclockwise rotation during the Late Miocene and earliest Pliocene. Here it is proposed that the western and eastern boundaries of the block are delineated by the Burdur-Fethiye Fault Zone and the dextral Antalya Fault, whereas the southern boundary is defined by the northern margin of the Sirri Erinc Plateau and/or the southern margin of the Anaximenes and Anaxagoras Mountains.
