Chemical study on clean chromites reveals enrichment of chromium and iron due to alteration. Physico-chemical properties show that alteration has enhanced the cell-edge, reflectivity and specific gravity but reduced the microhardness of the mineral. The reemplacement and subsequent instability of tectonic conditions might be the ultimate cause for the shift of Byrapur chromites from aluminian to ferrian field of composition.
