Abstract :

The Sabzevar ophiolite is a highly dismembered ophiolite complex located along the northern boundary of the central Iranian microcontinent (CIM), and is one of the internal Iranian group of ophiolites and colored melanges. The igneous rocks of this complex consist of peridotites (harzburgite, dunite and lherzolite), serpentinite, minor pyroxenite, gabbros, and a volcanic sequence that exhibits a wide range of composition from basalts and basaltic andesites to rhyodacite–dacites, rhyolites and basanites. Sedimentary rocks include a variety of Upper Triassic to Lower Cretaceous deep- and shallow-marine rocks. The study area located 30 km north of Sabzevar in 8 km north of the Zafaranieh village and Cheshmeh Sir village. Most rock of the area are harzburgite and dunite masses and have been moderate to severe serpentinitized. Geochemical stream sediment studies was perform. Geochemical analysis using AAS at Ferdowsi University of Mashhad for six elements including Cu, Cr, Mn, Co, Ni and Fe were performed. The results of analysis on the six elements show any anomaly.
