Abstract Podiform chromitites are unique rock units of ophiolites and ophiolitic melanges and represent invaluable repositories that reliably record the formation environment and evolution of their source and host rocks. However, there are relatively few podiform chromitites reported from Archean terranes. Here we document the major, minor, and trace

Origin of podiform chromitites
Journal of Asian Earth Sciences, 1997Abstract Podiform chromitite with a dunite envelope can be interpreted to be a product ofinteraction between mantle harzburgite and an exotic magma, combined with magma mixing. The secondary Si- and Cr-rich melt which is produced by the selective dissolution of orthopyroxene can be mixed with a subsequently supplied primitive melt with the mixed melt

Chromitite Deposits of Turkey in Tethyan Ophiolites
2019Some parts of the Tethyan ophiolites of Alpine-Himalayan suture belt are located within Turkey. The Tethyan belt splits into two branches in Turkey. The northern branch follows the Izmir-Ankara-Erzincan Zone, while the southern branch extends along the Anatolide-Tauride and Bitlis-Zagros suture zone. The subsections of the latter reach Iran in the east

Role of water in the origin of podiform chromitite deposits
Earth and Planetary Science Letters, 2002Abstract We report experiments in basalt oversaturated with water to duplicate the nodular ore textures of podiform chromitite ores. In immiscible basalt–water systems saturated with olivine and chromite, olivine will reside in the melt while chromite will collect in the fluid phase.

Abstract Chromitites found in layered intrusions and ophiolite complexes are generally enriched in platinum-group elements (PGE), especially IPGE ( i.e ., Ir, Os, Ru)-bearing platinum-group minerals (PGM), and the chromitites are usually poor in base metal sulfide (BMS) minerals.

Chromitite xenoliths from the Takashima alkali basalt in the Southwest Japan arc are classified into two types: Type 1 chromitite in thin layers in dunite or wehrlite xenoliths; and Type 2 chromitite in discrete xenoliths which has an orbicular texture, previously documented only from podiform chromitites in ophiolites.

A large number of podiform chromitite bodies of massive, disseminated and nodular type have been located in ultramafic units, composed of depleted mantle harzburgite and dunite of the Marmaris Peridotite from Ortaca (Mugla, SW Turkey). The chromite ore bodies are surrounded by dunite envelopes of variable thickness, exhibiting transitional boundaries ...
