Özet

Here we reassess the timing and amount of rotation of the eastern limb of the Aegean orocline, located in SW Turkey. The current model for this orocline involves a 25-30 degrees counterclockwise (CCW) rotation of the Bey Daglari region, which exposes upper Cretaceous to Eocene platform carbonates and lower Miocene flysch deposits. In this model the rotation has to postdate a Miocene remagnetization, which would not exclude non-synchroneity between rotations of the western and eastern limbs of the Aegean orocline. To test this model a detailed palaeomagnetic study was conducted on lower Miocene strata in the Bey Daglari area. Two (composite) sections were sampled near Korkuteli and Dogantas, spanning the lower Miocene foreland basin stratigraphy from the Aquitanian unconformity with the Bey Daglari limestones to the uppermost Burdigalian-lowermost Langhian, and a wide array of palaeomagnetic analyses were obtained.
