Electron Microprobe Investigation of the Dolomitization and Its Relationship with the Sulfide Mineralizations in the Polymetallic Deposits Confined to the Triassic Calcareous Sediments in the Western Balkans

The studies cover the two types of dolomites in the region of the deposits: the bedded dolomites and the metasomatic dolomites in bodies of irregular and varying shape. The second type of dolomites is characteristic for the ore deposits. They also occur outside the area of the ore deposits at varying distances from them, being always confined to fault dislocations.

For the metasomatic dolomitization, evidence of a repeated, polygeneration formation of the dolomite metacrystals is found everywhere. At certain stages, the formation of metacrystals involved iron which, in relatively higher amounts, resulting in the formation of ferroan dolomite and ankerite zones, is characteristic only of the dolomite associated directly with the sulfide mineralizations.

The bedded dolomites in immediate contact with the sulfide mineralizations are only slightly recrystallized.
