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 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.

Journal of Asian Earth Sciences, 2012
Abstract Two types of podiform chromitite, concordant and discordant, were examined in the mantle section of northern Oman ophiolite along Wadi Hilti, to revisit the structural classification of podiform chromitite. They are contrasted in mineral chemical characteristics, in addition to the difference in attitude; the Cr/(Cr + Al) atomic ratio of ...

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

Advances in the understanding of chromitite deposits
Applied Earth Science, 2009Chromitites in ophiolites and layered intrusions are the primary source of high quality chromium ore. Some chromitites can also carry significant concentrations of the platinum-group elements (PGE) and in the case of the Upper Group 2 (UG2) chromitite of the Bushveld Complex (South Africa) the PGE are the primary resource.

The Kemi stratiform chromitite deposit, northern Finland
Economic Geology, 1989The Kemi chromite deposit is hosted by an early Proterozoic (2.44 Ga) layered intrusion. The lower part of the intrusion is composed of peridotitic and pyroxenitic cumulates and chromitite layers. Olivine and chromite have not been observed in the upper part, where plagioclase is the predominant cumulus phase occurring either alone or together with ...

Abstract This paper details the mode of occurrence, petrography, and chemistry of mineral inclusions hosted in chromian spinels of the Neoproterozoic chromitites in the Southern Eastern Desert of Egypt. Neoproterozoic podiform chromitites from the Arais, Balamhindit, and Abu Dahr areas, in the Southern Eastern Desert, can be texturally and chemically
