Abstract

The intrusive bodies of Almogholagh Batholith, in western Iran are emplaced into the Sanandaj– Sirjan magmatic-metamorphic zone and comprise three main groups: (1) gabbro-diorite, (2) quartz syenite, and (3) quartz monzonite, which crop out in most of the area. The quartz syenite and quartz monzonite rocks, having characteristics such as metaluminous, generally ferroan, alkalic to alkali-calcic types, high content of Na2O+K2O, Zr, Ce, Ga, Y, Nb, Ta, REE, and depletion in Eu, Sr and Ti, show the features of borderline between A1 and A2-type granitoids with more A1-type affinity. On the basis of the results of the various diagrams, the gabbroic-dioritic rocks show between A1 and I-type granitoids nature with more I-type affinity. Distinctive peak patterns in spider diagrams accompanied by (La/Yb)CN values of 2. 4 to 6. 1 and Ba/La ratio >3 indicate magmatic activity in a volcanic arc environment, and the characteristics (Ba/Rb)CN<1, (Ba/Th)CN <1 and Th/Ta ratio from 1 to 20 suggest magmatic activity at a continental margin setting., Amphiboles is abundant in Almogholagh Batholith intrusive rocks and biotite is absent. Therefore, these bodies belong to post-collision setting. 143Nd/144Nd > 0. 512638, ε tNd >0, ε tSr >0, high content of Nb, Ta and very high content of Zr (589 ppm) indicate that there was a subsidiary Subduction after the initial collision for a long time and the magmas of Amogholagh batholiths were originated from mantle wedge, overlying the Subduction zone or from mantle components around fragments resulting from delamination between continental crust and mantle lithosphere, demonstrating the involvement of Subduction zone fluids, high flux of mantle-derived halogen-rich volatiles, and contamination within the crust during the Petrogenesis of intrusions.
