Abstract :

According to petrographical study, ultramafic rocks of ophiolitic melange in North-East Torbat-e Heydarieh are harzburgite, dunite, pyroxenite and serpantinite. The majority of the minerals of these rocks are orthopyroxen, olivine and clinopyroxene and with accessory mineral such as choromite and spinel. The geochemical study shows that origin of magma of these rocks is Mg- rich tholeiite. Plot diagram of these rocks demonstrates their perdotitic komatite type nature and belong to ultramafic cumulate ophiolite rocks and similar to depleted mantle peridotite found in ophiolites complex.
