“…The Upper Red Formation covers an extensive area in Central and NW Iran. This formation is composed of conglomerate, sandstone, red shales and marls with evaporates (Stö cklin, 1972;Asadian, 1993;Karimzadeh Somarin, 2004). The age of emplacement of the subvolcanic domes has not been determined by geochronological dating, but based on stratigraphical studies, these domes are Middle to Late Miocene in age.…”

“…Hezarkhani and Williams-Jones, 1998;Mohajjel and Fergusson, 2000;Karimzadeh Somarin and Moayyed, 2002;Karimzadeh Somarin, 2004b) indicates that Eocene-Oligocene volcanism, followed by Oligo-Miocene plutonism, resulted in the intrusion of granitic, granodioritic and gabbrodioritic plutons into earlier volcanic sequences. Cross-cutting relationships and the increasing dip of the volcanic layers in the vicinity of the contacts indicate that Mendejin pluton was emplaced forcefully.…”

Late Miocene-Pliocene to Quaternary calcalkaline lava flows and domes are exposed in southeast of Isfahan in the Urumieh Dokhtar magmatic belt in the Central Iran structural zone. These volcanic rocks have compositions ranging from basaltic andesites, andesites to dacites. Geochemical studies show these rocks are a medium to high K calc-alkaline suite and meta-aluminous. Major element variations are typical for calc-alkaline rocks. The volcanic rocks have SiO 2 contents ranging between 53.8% and 65.3%. Harker diagrams clearly show that the dacitic rocks did not form from the basaltic andesites by normal differentiation processes. They show large ion lithophile elements-and light rare earth elements (LREE)-enriched normalized multielement patterns and negative Nb, Ti, Ta, and P. Condrite-normalized REE patterns display a steep decrease from LREE to light rare earth elements without any Eu anomaly. These characteristics are consistent with ratios obtained from subduction-related volcanic rocks and in collision setting. The melting of a heterogeneous source is possible mechanism for their magma genesis, which was enriched in incompatible elements situated at the upper continental lithospheric mantle or lower crust. The geochemical characteristics of these volcanic rocks suggested that these volcanic rocks evolved by contamination of a parental magma derived from metasomatized upper lithospheric mantle and crustal melts.
