Abstract: The Maden complex crop out in the nappe zone of the Eastern Taurus orogenic zone extending for >1000km from Eastern Mediterranean to Iran. The Maden Complex consists of different sedimentary blocks and volcanic rocks. The volcanic rocks are presented by basalt, andesite, dacite. The age of the volcanic sequences have been assigned to Middle Eocene based on the fossils in sedimentary rocks. The U-Pb geochronology of one sample yielded an age 49∓3 Ma. Geochemical data indicate the presence of two different volcanic groups characterised by MORB-like and island arc tholeiite. Based on this data, it can be suggested an island arc and back-arc basin geotectonic environments. The geotectonical evolution of the Eastern Taurus indicate that there was a rifting during Late Triassic and subduction and collision from Late Cretaceous to Miocene.
