Figure 13. En-Wo-Fs diagram showing the compositions of pyroxenes from the rocks of the Aganozero (A) and Shalozero (B) bodies. 1 to 7 are pyroxenes from the layered series (1 - ultrabasic zone, 2 - main chromite unit, 3 - pyroxenite zone, 4 - gabbronorite zone, 5 - peridotite marker, 6 - pigeonite gabbronorite zone, 7 - magnetite gabbronorite zone); 8 is pyroxene from the marginal series.
