Chromite

The space group for a spinel group mineral may be Fd 3 m (the same as for diamond), but in some cases (such as spinel itself, MgAl 2 O 4) it is actually the tetrahedral F 4 3m.. Normal spinel structures are usually cubic close-packed oxides with eight tetrahedral and four octahedral sites per formula unit. The tetrahedral spaces are smaller than the octahedral spaces. B ions occupy half the ...

Introduction. A large body of data exists in the literature describing chromites from ophiolites, layered intrusions, kimberlites, basalts and other provenances, but relatively few studies have looked systematically at chromite in komatiites (e.g. Zhou & Kerrich, 1992).This is the first in a series of papers which addresses the occurrence of chromite in komatiites and its chemical variability.

Introduction. Discovered in 1797 by Louis-Nicholas Vauquelin and isolated a year later, chromium is a very hard steel-gray metal which takes its name from the Greek word chroma, for "color", suggesting the wide variety of colors which characterize its compounds, many of which are used as oil paint pigments. the pure metal is also a valuable alloying agent for spring steels and along with ...
