Abstarct: In the Goft area in southwest of Sabzevar, gabbro-diorite intrusions intruded into the late Cretaceous volcano- sedimentary sequence. The rocks of these intrusions usually have granular texture and their rock forming minerals are amphibole, plagioclase, pyroxene and quartz. These rocks have calc-alkaline nature and geochemical characteristics of igneous rocks of continental margin magmatic arcs. Also,the tectonic setting discrimination diagrams represent the relationship between these granitoid masses with the continental margin volcanic arcs (VAG). This arc has been formed by subduction of the Sabzevar Neo-Tethyan oceanic lithosphere under the northern edge of Central Iran- south eastern Alborz in the Upper Cretaceous-Eocene. Magma forming of these intrusions has been formed from partial melting of the subducted oceanic slab in the amphibolite facies. Mineral chemistry of all amphiboles plot in the range of igneous amphiboles. Amphiboles of dioritic samples are of calcic type with magnesium-bearing hornblende in composition. This mineral crystallized at pressures of 3 to 5.5 Kb (Approximate depths 8-10 km). The composition of the plagioclase in the gabbro diorite rocks varies from anorthite to labradorite. The temperature of equilibrium and closing of exchange for amphiboles and plagioclases is in the range of 859 to 970 ˚C. Pyroxenes are in the range of calcium, magnesium and iron-bearing pyroxenes and poor in sodium with augite composition. They formed from a primary magma in an environment with high oxygen fugacity. Clinopyroxenes have been crystallized at pressures of 2-5 kb with 10% water at about 1000-1150 °C. The mineral chemistries of the amphiboles and pyroxenes indicate the sub-alkaline nature and subduction related environment for these intrusions.
