In the paper, the chromite as well as external phlogopite and ferrodolomite are analyzed with such means as the point analysis with EPMA(electron probe micro-analyzer), map scanning and correlation analysis from the perspective of geochemistry. It is found from the analysis results that three annuluses can be seen inside and out of chromite, the contents of Al, Mn and Zn in the center are higher than those in outer ring as well as content of Fe in outermost ring is high, that is, the contents of Mn, Al and Zn are gradually decreased as well as content of Fe is gradually increased inside and out of the chromite. This indicates that the magnesium aluminate spinel should be formed firstly in this region, then it is replaced by fluorine-rich magma to chromite in later period, the fluorine-containing and silica-containing magma upwells into carbonatite dykes along channel as well as it is condensed into fluorine-containing phlogopite at the same time. The conclusion consistent with the above could be obtained with the Pearson correlation analysis, that is, there are negative correlations between FeO and Cr2O3, MnO, ZnO and Al2O3, which shows that there is isomorphic substitution among them.
