Öz The Karadağ volcanic succession of Pliocene and Oualernaiy represents typical Continen­ tal volcanisms of central Anatolia. It consists of nıainîy lava flows and pyroclastic depositş. Overall, they Avere produced by magmato-phreatic e.Kplosions in four periods throiıgh the plioce­ ne and Çuaternay times. The product of each period can be easiîy distinguished by vvcathering surfaces and localiy erodcd surfaces. Petrographical and geochemical analysis show that they are mostly andcsitic and dacitic roeks, originated from partial rnelting of Continental crust.
