Twenty one magmatic rocks were analyzed for major and trace elements,and asubset of them for Sr-Nd isotopes and zircon U-Pb isotopes,to constrain magmagenesis and tectonic evolution of the Iranian segment of the Makran arc.Two samplesfrom the Bazman volcano yield zircon U-Pb ages of 7.5±0.1Ma and 5.9±0.2Ma.Four samples from the Taftan volcano yield a cluster of ages at ～3.4-3.2Ma and onesample was dated at 0.84±0.06Ma.The obtained ages are consistent with thepublished K-Ar and39Ar/40Ar ages for these volcanoes ranging from the Late Mioceneto the Late Pleistocene.The Mirabad granitic pluton,which is close to and interpretedto be the root of the Taftan volcano,was dated at～19Ma.Theanalyzed rocks showbasaltic to rhyolitic compositions,calc-alkaline affinity and an orogenic geochemicalsignature revealed byenrichments in large ion lithophile elements,light rare earthelements and Pb,and depletions in high field strength elements andP relative toelements of similar incompatibilities.
