Аннотация:The paper presents compositional analysis of chromite and inclusions in it from the chromitite layers of the Bushveld Complex. The chromite composition remains constant throughout the 1.5 km cross-section of
the complex. The inclusions in chromite and interstitial paragenesis are extremely variable in mineral composition, which does not correspond to the magmatic cumulus origin of chromitites. A number of minerals are not typical for the ultramafic rocks, but many of them are usual minerals for placer deposits and are stable in the near-surface conditions. The authors assume that chromitite horizons are essentially the metamorphosed placer deposits formed more than two billion years ago.
