Major rock units of Robat Sefid ophiolitic complex are Late Cretaceous in age. The abundance of rock units in this area in ascending order are: dunit, harzburgite and pyroxenite), gabbro and diabasic dikes (mostly rudenginized). Chromite lenses are generally covered by a few centimeters to several meters of ultramafic rocks mainly of dunite. Primary disseminated and massive textures are abundan...

The occurrence of rhythmic layering of chromite and host serpentinites in the deformed layered igneous complexes has been noticed in the Nuggihalli schist belt (NSB) in the western Dharwar craton, Karnataka, South India. For this study, the chromitite rock samples were collected from Jambur, Tagadur, Bhakatarhalli, Ranganbetta and Byrapur in the NSB. Petrography and ore microscopic studies on c...

based on existence of the chromite deposits in the sistan and baluchestan province in iran, and also various applications of chromite in different industries, it is expected that the establishment of chromite processing plant is required in the erelong. the geographical location of a processing plant can have a strong influence on the success of an industrial venture. the processing plant site ...

The podiform chromitite deposits of the Ordovician Sorkhband ultramafic complex, southwestern Makran, are the largest chromitite deposits in Iran. The Sorkhband ultramafic complex comprises of a northern part of dunite, podiform chromitite, olivine clinopyroxenite, wehrlite and olivine websterite and a southern part of foliated diopsidic harzburgite with subordinate dunite, olivine clinopyroxen...

Chromite is a strategic mineral resource for many countries, and chromite deposit occurrences are widespread in the ultramafic rocks of Yarlung Zangbo ophiolite belt, particularly harzburgite unit mantle section. Conducting field surveys complex poorly accessible terrain challenging, expensive, time-consuming. Remote sensing an advanced method achieving modern geological work powerful technical...
