Figure 11. Triangular diagram for the composition of ore and
metamorphosed accessory Cr-spinel from the Rai-Iz Massif. I - Ore
Cr-spinel; 2 - compositional field of Cr-spinel in various ore types:
II - lean disseminated metamorphosed Cr ore; III - Cr ore in the rocks
of the DH complex; IV - ores of the Tsentralnoe and Zapadnoe deposits;
V - high-Al Cr ores in the rocks of the H complex; 3 - accessory Cr-spinel
of the chromite-magnetite series (ferro-ferri-chrome spinel); 4 - miscibility
gap in the chromite-magnetite series (Mössbauer and IR spectroscopic
data).
