The chromite pyroxenite nodules of Kondapalli region were brought from deeper levels of the earth by spinel pyrofenite magma during cross folding in the Eastern Ghats. The spinel pyroxenites were transformed into the mineral assemblage: serpentine-gamet-magnesite-calcite-quartz, due to the activity of volatiles derived from the regions of magma generation. The Ni coptent (1,050-1,100 ppm) in the serpentines and magnesites support pyroxenite parentage.
