Gabbroic complex of Soltan Abad is Located about 35 Km east of Sabzevar. According to tectonic classification, the study area is part of Sabzevar ophiolitic zone. The composition of these intrusion bodies are vary from gabbro to gabbro-diorite. The main minerals of gabbroic rocks are plagioclase (bytonite), clino-pyroxene and ortho-pyroxene (enstatit – hyperestene) and accessory minerals are ap...

Nosrat-Abad ophiolitic extrusive sequence, located in the Sistan Suture Zone, in south eastern Iran. The extrusive sequence, contains pillow lava, sheet flow and related volcanic-clastic breccias which have undergone low-grade metamorphism. This association shows calc alkaline to tholeiitic affinities. Interpretation of the geochemical data and behavior of the elements in different diagrams rev...

Mafic–ultramafics complexes are crucial for their tectonic implication, upper mantle condition, and hosting industrial minerals in a region. This study aims to highlight characterize the mafic–ultramafic rocks of Logar Ophiolite Complex using integration geospatial technology field data. The spatial distribution ophiolitic complex was examined this mineralogical indices (MI), band ratio (BR), s...

The Tibetan Plateau holds clues to understanding the dynamics and mechanisms associated with continental growth. Part of the region is characterized by zones of ophiolitic mélange believed to represent the remnants of ancient oceanic crust and underlying upper mantle emplaced during oceanic closures. However, due to the remoteness of the region and the inhospitable terrain many areas have not r...
