Abstract :

According to petropgraphical and geochemical study, mafic intrusive unit of ophiolitic melange in North-East Torbat-e Heydarieh are gabbro and gabbrodiorite.The majority of the minerals of these rocks are plagioclase, clinopyroxene and hornblende that in some samples occurs uralitization in pyroxenes and sericitization and saussuritization in plagioclase and amphibols convert to cholorite. The constituent magma is subalkaline and in AFM diagram plot in tholeiitic field and is type of high Mg-tholeiitic field .Tectonic discrimination diagrams show affinity this rocks to mid oceanic ridg (MORB).
