Hydrothermal Chromitites from the Oman Ophiolite: The Role of Water in Chromitite Genesis

Minerals, 2020
The role of water-rich solutions in the formation of chromitites has been the matter of controversy. We found small chromite concentrations (chromitites) in diopsidites, precipitated from high-temperature hydrothermal fluids, in the mantle to the crust ...

Chromite and platinum group elements mineralization in the Santa Elena Ultramafic Nappe (Costa Rica): geodynamic implications [PDF]

Geologica Acta, 2011
Chromitites associated with strongly altered peridotite from six distinct localities in the Santa Elena ultramafic nappe (Costa Rica) have been investigated for the first time.

Investigation of Petrological Characteristics of The Upper Mantle in Hadji-Abad Ophiolitic Complex (South of Iran): Based on Mineral Chemistry [PDF]

Journal of Sciences, Islamic Republic of Iran, 2021
The mantle peridotites of the Hadji-Abad ultramafic complex in Hormozgan province, show some petrological evolutions of the upper mantle of southern Iran. The complex includes harzburgite, lherzolite, dunite and chromitite.

the origin of Abgarm ultramafic complex (South of Kerman province) [PDF]

پترولوژی, 2020
Abgarm ultramafic complex in the south of Kerman province is a part of Esfandagheh- Haji Abad ophiolite which is located in the northern edge of Zagros thrust. The complex contains harzburgites, lherzolites, dunites, and chromitites.

Stratigraphic variations in chromite chemistry through the UG-2 and UG-2E chromitites, bushveld igneous complex: implications for chromitite petrogenesis

Soviet Economy, 2023
Chromitite petrogenesis in layered intrusions is important because some chromitites host economic Ni-Cu-platinum group element mineralization. Cryptic layering, which could be useful to reconstruct the chromitite origin, has been documented for some ...

FTIR study of H2O in silicate minerals and mineral inclusions in chromite from the peridotite zone of the Stillwater complex (Montana, USA): Evidence for chromitite formation in an H2O-rich environment

Geological Society of America Bulletin, 2023
Although the involvement of hydrous fluids has been frequently invoked in the formation of stratiform chromitites in layered intrusions, there is a lack of natural evidence to signify their presence and mechanism.

Post-magmatic processes recorded in bimodal chromitites of the East Chalkidiki meta-ultramafic bodies, Gomati and Nea Roda, Northern Greece

Frontiers in Earth Science, 2022
The meta-ultramafic bodies of Gomati and Nea Roda are situated in the Serbomacedonian Massif. They demonstrate bimodal character in terms of chromitite chemistry with both Cr- and Al-rich chromitites outcropping in proximity, with no obvious tectonic ...
