Possible sub‐arc origin of podiform chromitites
Island Arc, 1995 Abstract The sub‐arc mantle condition possibly favors the formation of podiform chromitites. The Cr/(Cr + Al) atomic ratio (= Cr#) of their chromian spinel frequently is higher than 0.7, which is comparable with the range for arc‐related primitive magmas. This almost excludes the possibility of their sub‐oceanic origin, because both oceanic peridotites

, 1979 The central issues in petrology have remained remarkably unchanged in the last 50 years. In igneous petrology, the focus is on understanding the nature and cause of diversity in igneous rocks: on identifying primary magma types and constraints on the ...

Earth and Planetary Science Letters, 2013 AbstractPodiform chromitites have been interpreted as a peridotite/melt reaction product within the upper mantle (= low-P chromitites). Some of them, however, contain ultrahigh-pressure (UHP) minerals such as diamond and coesite (= UHP chromitites). The UHP chromitites can be produced by deep recycling of low-P chromitites via mantle convection. Carbon-

Geologica Acta, 2015 The Mesoarchean chromitites in the Singhbhum craton provide the main source of chromium in India. We report here results of dating zircon grains that were found in the chromitite of ultramafic rocks belonging to the southern part of the Archean Baula ...

Platinum group element mineralization at Musongati (Burundi) : concentration and Pd-Rh distribution in pentlandite [PDF]
, 2017 The mafic-ultramafic intrusions of the Karagwe-Ankole belt in Burundi are considered as a new potential source for platinum group elements (PGE). The intrusions have mainly been studied for their PGE potential with regard to PGE concentration, but the ...

Ophiolite-Related Ultramafic Rocks (Serpentinites) in the Caribbean Region : a Review of their Occurrence, Composition, Origin, Emplacement and Ni-Laterite Soil Formation [PDF]
, 2006 Ultramafic rocks, mainly serpentinized peridotites of mantle origin, are mostly associated with the ophiolites of Mesozoic age that occur in belts along three of the margins of the Caribbean plate. The most extensive exposures are in Cuba. The ultramafic-

Chromian spinel geochemistry as a petrogenetic indicator in the chromitites and peridotites of the Bajgan Complex, Western Makran [PDF]
پترولوژیIntroductionEconomic chromite deposits are very common in ophiolite belts. These deposits usually occur in the uppermost horizons of the ophiolite mantle sequence or within the ultramafic cumulitic rocks at the base of the crustal sequence (González ...
