Özet

Isotopic and thermochronological data were recently obtained from the footwall of the Buyuk Menderes detachment ranges from 29.0 +/- 1.9 Ma (ZFT) to 1.6 +/- 0.2 Ma (Ap U - Th / He), and they can be grouped in three different time intervals. These results are well explained by the Alasehir type-rolling hinge mechanism, which suggests active rotated initial normal fault during successive normal fault development of the graben formation. This paper suggests that the Alasehir type-rolling hinge mechanism is applicable to the Buyuk Menderes graben by using field observations, published isotopic / thermochronological and subsurface data. It also contributes to the long-lasting discussion about the activation problem on the low-angle normal faults.
