Abstract. Mossbauer measurements have been carried out on three natural chromite minerals from different locations in China over the temperature range 50 to 750 K. The experiments showed these samples to be magnesioferrochromites. The Mossbauer spectra measured could be decomposed into three doublets: two attributed to the tetrahedral T-site Fe 2 + ions and the third to the octahedral M-site Fe 3 + ions. Thus for the chromite spinels the results strongly supported the ordered distribution with Fe 2 + in the T-site and Fe 3 + in M-site.
