Western Turkey is characterized mainly by E-W, NW-SE, and NE-SW-trending grabens. The reverse V-shaped geometry of the Baklan-Dinar graben is formed by coupling of the NE-SW-trending Baklan and the NW-SE-trending Dinar grabens, and is critical to an understanding of the structural evolution of the Aegean region. Its geometry indicates biaxial extension in the region, as proposed in the current literature (e.g. Temiz et al. 1997; Cihan et al. 2003). The Acgl and Burdur grabens parallel the axis of the Baklan graben in the south, and these three basins terminate against the Dinar fault. The Baklan Basin is bounded along both margins by the Baklan and al left-lateral oblique faults. Basin-fill deposits of the Baklan Basin thicken towards the Dinar fault, and the basin floor dips northeastward. In addition, geomorphological characteristics of the Baklan-Dinar graben indicate that the Dinar fault is relatively more active than the faults of the Baklan Basin. All available morphologic, structural, borehole, and geophysical data from the Baklan-Dinar graben define a cross-graben structure that developed during Plio-Quaternary uniaxial NE-directed extension in SW Turkey. In this framework, the Dinar fault plays the role of a breakaway fault of this formation. The increase in the normal components of the northwestern left-lateral oblique basin-bounding faults of the Baklan Basin is explained by the gradual steepening of the pitch of the slip vectors towards the northeast, because of capturing of the extension by the Dinar breakaway fault. © 2012 Copyright Taylor and Francis Group, LLC.
