Chromite and chromite chondrules in meteorites—I

Geochimica et Cosmochimica Acta, 1967
Abstract In a number of chondrites, several chondrules have been found containing chromite as a major component. The second, most common mineral in these chondrules is usually an albite-like plagioclase. Besides coarse grains of chromite, many chondrules contain fine chromite grains, intergrown with feldspar as pseudomorphs after a previously ...

Light Mg isotopes in mantle-derived lavas caused by chromite crystallization, instead of carbonatite metasomatism

Earth and Planetary Science Letters, 2019
Carbonatite metasomatism plays an important role in modifying the composition of Earth's mantle, however, its effect on mantle Mg isotopic composition is poorly constrained.

Initial subduction of Neo-Tethyan ocean: Geochemical records in chromite and mineral inclusions in the Pozantı-Karsantı ophiolite, southern Turkey

Ore Geology Reviews, 2019
Chromitites in the Pozanti-Karsanti ophiolite in Turkey mainly occur as podiform chromitites within mantle harzburgite and stratiform-like chromitites in mantle-crust transition zone.

Chromite-Rich and Chromite-Poor Ophiolites: The Oman Case

1991
Chroinite deposits in Oman belong dominantly to the concordant structural type, meaning that these have been intensely deformed by plastic flow and tectonically rotated to become parallel to the peridotite foliation. This occurred soon after their formation within the transition zone below the ridge of origin. Subconcordant and discordant pods are also

Chromite-periclase roof articles

Refractories, 1996
An investigation of the technology for chromite-periclase roof articles is presented. With a scarcity of periclase powders compositions with 25–30% granular chromium ore and 35% finely milled mixture of periclase and chromite seem a suitable material for chromite-periclase roof linings. It is possible to use charges with 65% scrap.

Carbothermic reduction of chromite fluxed with aluminum spent potlining

Transactions of Nonferrous Metals Society of China, 2019
Aluminum spent potlining (SPL) was employed as both the fluxing agent and a source of carbonaceous reductant for the carbothermic reduction of chromite, aiming to allow effective separation of alloy from the slag component.

Indian chromites [discussion]

Economic Geology, 1966
Relative to a paper by K. L. Chakraborty on the geologic and mineralogic characteristics of chromite occurrences in India (for reference, see this Bibliography Vol. 30), the age of the country rocks is questioned, as well as the degree of alteration of the dunite host, the evidence for injection of chromite, and the high alumina content of all Indian ...

Minor and trace element variations in chromite from the Songshugou dunites, North Qinling Orogen: Evidence for amphibolite-facies metamorphism

Lithos, 2019
The Songshugou dunites are part of the ultramafic sequence of the Songshugou ophiolite within the Qinling Group metamorphic rocks, which are distributed in the northern part of the Shang–Dan Suture Zone (SDSZ) in central China. The dunites include lenses
