Chromespinel and Magnetite as Indicators for Recognition of Genesis and History of Serpentinites in Baft Ophiolite Mélange (Kerman Province in Iran) [PDF]

Journal of Sciences, Islamic Republic of Iran, 2013
Baft ophiolite mélange is a part of Naein-Baft ophiolite (southeast of Kerman province in Iran). Serpentinites from Baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal ...

Microstructural Insights into the Evolution of Ophiolitic Chromite from Luobusha

, 2023
The podiform chromitite found within the Luobusha ophiolite comprises characteristic nodules and massive chromitites. However, the exact origin of these formations remains a topic of ongoing debate.

Using trace elements in chromites to constrain the origin of podiform chromitites in the Thetford Mines Ophiolite, Québec, Canada

, 2009
The Thetford Mines Ophiolite is interpreted as a fragment of a fore-arc oceanic lithosphere. This complete ophiolitic sequence consists of a thick mantle sequence, a plutonic crustal component, and a volcano-sedimentary sequence dominated by boninitic ...

The Geochemistry of podiform chromite deposits from two ophiolite complexes, Chalkidiki peninsula, Northern Greece [PDF]

, 1980
The geochemistry of various petrological units from two mafic-ultramafic complexes, from the Chalkidiki peninsula have been studied. These complexes have been tectonically incorporated into the metamorphic country rocks, forming allochtonous bodies ...

Neoproterozoic ultramafic and mafic magmatism in the Eastern Cordillera of the central peruvian Andes: the Tapo Massif

, 2010
A highly dismembered assemblage of ultramafic and mafic rocks is exposed in the Eastern Cordillera of the Central Peruvian Andes, extending along a discontinuous NW-SE belt over some 250 km between 12° and 9° S of latitude.

Podiform chromitites in the Luobusa ophiolite (Southern Tibet): Implications for melt-rock interaction and chromite segregation in the upper mantle

, 1996
The Luobusa ophiolite in the Indus-Yarlung Zangbo suture of southern Tibet hosts the largest known chromite deposit in China. The podiform chromitites occur in a well-preserved mantle sequence consisting of harzburgite with abundant lenses of dunite. The
