Abstract: Pyroclastics exposed in the northern and northeastern parts of Çiftehan, present a complex structure together with alteratedbasaltic and andesitic volcanics. Pyroclastics were generally formed as tuff, agglomerate and volcanic breccia and intersected by trachyteand basaltic dikes extending in the east-west direction.According to their mineralogical composition, the volcanics wich are generally spilitized are of calkalkaline character. Their regionalsetting and major and some trace element constituahts show that the volcanics could be produced from a maturated island arc volcanism.
