Journal Article: Late Cenozoic Volcanic Evolution Of The Northeastern Aegean Region

Abstract
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.
