英文摘要	The granitoid bodies is located 120 km north-east of Shahrood town. The area is structurally located in the north of the central Iranian zone. These activities occurred during the Upper Eocene stage. This article describes a compositional study on biotites, plagioclase of monzonites of the granite rocks of Torud area and elucidates the geotectonic and geothermobarometry conditions. The main minerals of granitoids are quartz, plagioclase, and K-feldspar. Other constituents of these rocks are biotite, amphibole, sphene, and opaque minerals. Various textures such as granular, myrmekite and graphics are observed in these rocks. Based on the geochemistry studies Plagioclase monzonite, Quartzmonzonite rocks of range anorthoclase and granite rocks are in the range of albite. Biotite compositions in the granitoid bodied depend mostly on temperature of crystallisation and oxygen fugacity (fO(2)) and compositions of magmas from which they have been crystallised. The calculated Ti in biotite temperatures for the Troud granitoids are in the range of 530-900 degrees C. The biotite compositions used to discriminate tectonic settings of granitoids. The biotite compositions were used to discriminate the tectonic setting of the plutons. biotites granitoid rocks are the type of magmatic, rich in iron- magnesium, anorogenic alkaline and areas tensional. Based on the Major and trace element granitoid rocks different trends is show by Rb with Si and Ba with Si indicate occurrence of fractional crystallization processes (AFC). Based on the petrography, geochemistry and desert studies of the calc-alkaline, metaluminous, and series I granitoids, it can be inferred that the volcanic arcs of the continental margin are the orogenic areas that have originated from the partial melting of crust igneous rocks. The intrusions appeared to be related to calc-alkaline orogenic suites. granitoid rocks are associated with the subduction zone neotethys.
