In this study, we report the first robust apatite (U-Th)/He thermochronology data from the syn-extensional Eybek, Solarya and ?ataldag? plutons from NW Turkey. The Solarya and ?ataldag? plutons display similar (UTh)/He apatite ages which range from 21.5 ? 1.6 to 12 ? 1.9 and 22.4 ? 1.2 to 13.7 ? 1.3 Ma, respectively. The Eybek Pluton, on the other hand, yielded younger (U-Th)/He apatite ages between 8.4 ? 1.9 Ma and 5.6 ? 0.5 Ma. Exhumation rates of the plutons change between 214 m/Myr and 122 m/Myr. The exhumation rates and thermal modelling results show that the Solarya and ?ataldag? plutons experienced fast uplift and exhumation from early to middle Miocene. A low angle detachment fault(s) associated with ?ataldag? Metamorphic Core Complex was responsible for the exhumation of the ?ataldag? and Solarya plutons. In contrast, late Miocene cooling and exhumation of the Eybek Pluton was controlled by high angle normal faults. The collective evaluation of our data together with published low-temperature thermochronology data obtained from the spatially associated basement rocks and the metamorphic core complexes indicate that the region-wide exhumation of NW Anatolia was accommodated by different fault systems throughout the Miocene. We infer that the crustal exhumation in northwestern and centralwestern Anatolia occurred contemporaneously during the Miocene, and developed as a result of back-arc extension driven by slab roll-back beneath Hellenic arc and the preceding thermal weakening of the western Anatolian orogenic crust.
