Abstract

The Bibi Maryam ophiolite suite in the north of Nehbandan fault zone, East of Iran, is a part of Nehbandan Ophiolitic Complex with Cretaceous age. Mafic rocks of this suite are basalt, diabase and gabbro. Lack of metamorphic rocks of greenschist, blueschist and amphibolite facies, absence of cumulate peridotite and gabbro in spite of occurrence of mantle peridotite and isotropic gabbro, absence of discrete diabase sheeted dikes, scarcity of pelagic limestone and radiolarian chert, and enrichment of mafic rocks in incompatible elements and LREEs in comparison to normal MORB are indicative of the immature nature of the Bibi Maryam ophiolite suite. The primary magma of the mafic rocks has been abyssal tholeiite. The average amounts of TiO2 and K2O are 0. 47 and 0. 19, respectively, indicating the magma has been of NMORB type. However, regarding the trace element and REE contents of the mafic rocks, the magma should have been enriched in incompatible elements compared to NMORB. Based on these geological and geochemical evidence, the Nehbandan fault zone is thought to be an aborted mid-ocean rift.
