Special features of manganese mineralization in the metamorphic complexes
The results of mineral composition's research of the Utkhum and Ir-Nimi manganese-bearing occurrences were showed in this paper. The primary manganese-bearing sediments were metamorphized to different degrees. The comparison of silicate and carbon-bearing-silicate manganese ores, which are localized in different metallogenic provinces, allowed us to estimate of the geological situation's influence to forming of the stable mineral associations, including the influence of hydrothermal activity to special features of sulphide mineralization. Key words: manganese ores, technological mineralogy, metamorphic complexes.
