Abstract

ABSTR A C T A dense grid of high-resolution multichannel seismic reflection profiles are used to delineate the stratigraphic and structural architecture of the Anamur-Kormakiti zone which separates the Outer Cilicia Basin from the eastern Antalya Basin. The data showed that the uppermost Messinian-Quaternary structural framework of the region is characterized by two arcuate south-convex sinistral strike-slip fault zones in the northeast and east which converge to form a-70-80 km wide NW-SE trending zone, consisting of two internally-parallel dextral strike-slip fault zones in the northwest and west. A narrow NNW-SSE trending zone occupied by similarly trending positive flower structures across the Anamur-Kormakiti zone suggests that this region is probably a rotational stepover between two oppositely moving strike-slip fault zones. The regionally extensive strike-slip fault zones are largely developed during the Pliocene-Quaternary along the southern fringes of the Taurus Mountains in response to the westward escape of the Aegean-Anatolian Microplate following the collision and suturing of the Arabian Plate to the Eurasian Plate during the end of Miocene-Early Pliocene.
