Late Cenozoic volcanism occurred in an extensional tectonic regime in the northeastern Aegean Activity commenced in northeastern Greece during the Early Oligocene, and in northwestern Turkey during the Late Oligocene-Early Miocene. The beginning of activity was characterized by calc-alkaline intermediate-acid volcanism; however, alkaline intermediate-basic volcanism became dominant from the Late Miocene until the Pleistocene. This change in nature of volcanism is not related to a change of regional tectonic regime, as previously thought. Instead, we propose that the volcanic evolution reflects an increasing asthenospheric contribution, facilitated by a thinned, extended lithosphere arising from the regional extensional tectonics.
