rvater Complex, Montana. We have analyzed two parent chromite-ferritchromit pairs from the Stillwater Complex b1'a combination of wet and microprobe methods; both parent chromite and ferritchromit can be expressed by the general formula (Mg, l-e,+) (Cr, Al, Fe3+)rOr, and neither contains cation deficiencies of the maghemite Size: 1MB.
