Abstarct: Damghan and in northern part of Central Iran structural zone. This magmatic complex includes a wide variety of intrusive, extrusive and subvolcanic rocks. This investigation includes a detailed evaluation of intrusive and subvolcanic rocks of this magmatic complex which exposed such as stocks or dikes. The studied rocks have compositional range of Gabbrodiorite, Monzonite, Granodiorite and Granit. Intrusion of these plutons into host rocks (fossiliferous cretaceous limestone and volcano-sedimentary and nomolitic limestones of middle Eocene) has been acompained by contact mextamorphism, mextasomatism, hydrothermal, altheration and ore mineralization Garnet and garnet–vesuvianite skarns, magnetite mineralizatione and lead, zinc, copper and gold ore deposite confirm this subject. The studied rocks have high potassium calk-alkaline nature and mataluminous to alitle peraluminous. In variation diagrams there is a continuous trend between the mentioned rocks and indicats that they evolved by fractional crystallization. These rocks belong to I type, volcanic arc and Continental arc granitoids. Comparison the geochemical characteristics of these rocks with geochemical characteristics of adakite , show that these plutonic rocks of north of moalleman are high silica adakites which originated from partial melting of subducted oceanic slab.
