Abstract New trace-element, radiogenic Sr-Nd-Pb isotopic and geochronological data from Middle-Late Cretaceous Zagros ophiolites of Iran give new insights into the tectono-magmatic history these supra-subduction zone (SSZ)-type ophiolites. The distribution SSZ-type in comprises two parallel belts: (1) outer ophiolitic belt (2) inner belt. These were generated by seafloor spreading what became f...
Ophiolitic complex of Sahneh could be considered as part of ophiolite sequences in the Zagros Suture Zone.This complex is a part of 3000 km belt, which is started from Syria after crossing south Turkey and Zagros leading to Oman. The studied ophiolitic complex is curvature in shape which is situated in south of Sahneh. No complete ophiolite sequence were seen in this complex. In general, t...
There are metabasite exposures inside ophiolitic belt of northwest Sabzevar that metamorphosed under high pressure granulite facies. On the basis of mineralogical paragenesis, reactional textures between different mineralogical assemblages, textural and mineralogical relations between inclusion and porphyroblast and stability fields of different mineralogical assemblages, five stages of evoluti...
Abstract The Zagros orogen, formed by the collision of Arabian and Eurasian continental margins, represents one largest richest oil gas provinces in world. fold-thrust belt records convergence along Neotethys suture zone. By coupling field observations, sandstone modal analysis, U-Pb zircon dating, Hf isotopic data from Upper Cretaceous to Pliocene sedimentary succession Neyriz region, this pap...
The Kermanshah Ophiolite Complex (KOC) lies in the structural – tectonic zone of western Iran in northern part of Zagros main thrust and is a part of highly dismembered Kermanshah – Panjvin Ophiolitic belt. The best outcrops of the sheeted and isolated dykes in this complex are present in south of Sahneh area. They are basic in composition. The geochemical studies show parent magma is in its in...
