Abstract: This study aimed to determine the petrographic and geochemical features of the Plio-Quaternary Gözucu(Taşlıçay-Ağrı) volcanics. These volcanics have subalkaline, calc-alkaline, high-K-series and shoshonitic featuresand are composed of basalt, andesite, trachyandesite, trachydacite and dacites. The Gözucu volcanics exhibitenrichment in light rare earth elements (LREE) and large ion lithophile elements (LILE) while showing depletionin heavy rare earth elements (HREE) and high field strength elements (HFSE). The average Sr and Ba values ofGözucu volcanics are close to continental crust values (Sr-379 ppm Ba-639 ppm), which means that these rockswere contaminated by the continental crust during formation. Low Nb/La (5.13 ppm) and high Ba/Rb (16.75 ppm)ratios indicate that the contribution of sediments was more than that of fluids during the contamination process ofthe Gözucu volcanics. Positive and negative trends of major and trace elements in the variation diagrams indicatefractional crystallization and a single mantle source. The Gözucu volcanics occurred with a partial melting of thespinel-rich lithospheric mantle source with 0.1-3% partial melting in the continental arc environment after thecollision.
