Abstract:Based on the occurrence of Dongchinling-shonshugou ultramafic rock and the characteristics of the chromite mineralization as well as the mineral components, a comprehensive explanation of the mineralization characteristics of the various chromites, such as those of being as the accessory minerals and those of different types of ore, has been proposed through the analyses of Mossbaur spectra. In addition, the macroscopic and microscopic gelogical analyses of the mineralizatin of chromite leads to conclusion that the chromite ore body is actually the extreme portions of rich chrome and rich magnesium formed by the highly-melted pyrolite.
Key words: ultramafic rock chromite Mossbaur spectra pyrolite
