| Abstract: | The microstructures of magnetite containing vanadium and titanium, found in Panzhihua, China, were examined by high resolution electron microscopy (HREM).The 1(?)0] structural images showed the intermate intergrowth of mag netite and coulsonite along the 110] direction instead of the 111] direction, as reported previously, as a result of the exsolution of coulsonite in the matrix. The 110] antiphase domain and various stacking faults related to the nonstoichiometry of the transition metal oxides were also observed in magnetite and coulsonite, respectively. The possible genetic aspects of these defects and effectiveness on the exsolution of coulsonite are discussed as well. |
