Abstract :

Study area is belt shape with trending NW-SE, situated in north Doruneh fault Central Iran Zone and located northeast of Iran. The main geological characteristics of this region are the presence of Tertiary rocks consist the Paleogene volcano-sedimentary complexes and the thick and vast units of Oligocene-Neogene detrital sediments, which especially igneous Paleogene series are important. Duration of Tertiary magmatic activities is characterized by a spectrum of Paleocene-Eocene volcanic and pyroclastic rocks of intermediate composition and intrude most of plutonic body in Late Eocene-Early Oligocene. Geochemical characteristics of Tertiary igneous rocks in region shown K2O, Na2O, CaO values are high and Geochemistry study of the main element shows calk alkaline and manifest tendency alkaline magmatism.
