Abstract
The chromitite lodes are emplaced in serpentinites as banded layers, lenses or clots. The ores are high alumina chromite with RO:R
2O
3 ranging from 0.92 to 1.08 and formed by magmatic segregation.
Hydrothermal alteration has produced different chrome-bearing silicates like kammererite, uvarovite, chrome-amphibole, and chrome-bearing chalcedony, which occur either as transgressing veinlets in chromitites or in the interspaces between chromite grains. The primary dunite-peridotite has been altered to massive and compact serpentinite.
