Abstract: Petrologic analyses of the volcanics in Gördes (Manisa) region is used in interpretation of origin andplate tectonics of Western Anatolia. Late Miocene volcanisoa is dacitic, rhyodaeitic and rhyolitic with a calcalkaline affinity. Petrochemical characteristics of the Gördes volcanics point out to the fact that they might be originatedfrom continental crust as a result of anatexis.
