Abstract: Volcanic rocks of Lower Jurassic age, which crop out in the southeast of Akhisar, haverecently been identified. They are intercalated with marine deposits, with characterize a shallowwater enviroment. Greenish compact meta-volcanics are petrographically rhyolitic. Major elementanalyses indicate that they are calc-alkaline in character.Distribution and the localitions of the Triassic and Jurassic volcanics which crop out in West Anatolia, Aegean islands and the mainland Greece are summarized on the map. Triassic volcanics aremainly spilitic and basaltic. Differentiated products are subordinate. Jurassic volcanics consist of spilitic, basaltic, andesitic and dasitic rocks.Their petrochemical character and mode of occurance are discussed in order to understand therelation between the feodynamic evolution of the region and the genesis of the volcanism during theEarly Mesozoic.On consideration of the data, the products of Triassic-Jurassic volcanism seem to be related torifting and subduction processes.
