Abstract
M isho A-type granite body is located in 60 km NW of the Tabriz and SE Marand which has been intruded along Misho North Fault into the Kahar formation. This pink to gray body contain felsic minerals include quartz, K- feldspar, plagioclase and mafic minerals such as biotite and amphibole. General textures in these rocks are medium to coarse granular, pertite, myrmekite, rapakivi and graphic. These rocks have high contents of SiO 2 , Fe 2 O 3 t/MgO, K 2 O Na 2 O, Rb, Ga, Zr and LREE and low contents of CaO, MgO, Ba, Sr and depletion of Nb and Eu. These rocks are peraluminous to peralkalin and plotted in the ferroan and alkaline-calcic to alkaline fields on FeO/(FeO+MgO) vs. SiO 2 and [(Na 2 O+K 2 O)−CaO] vs. SiO 2 diagrams. Based on geochemistry classification, the A-type granites belong to the A 2 subgroup and formed in post collision setting in active continental margin. This body has been cut by basic dyke with dark color. Dyke geochemistry data show it is calk-alkaline. Based on the use of the isotopic ratios, the high consistent of 87 Sr/ 86 Sr(i) and negative values of ε Nd(t)of granites accords the ratios belonging to the lower crust.
