Аннотация:Specific features of chemical composition, isomorphism and zonality of pyrochlore supergroup minerals (PSM) from metasomatic rocks of the ore body No. 9 (Pelagonian massif, Macedonia) have been was studied. The ore body No. 9 bears unusual nonsulfide association of chalcophilic elements Zn, As, Sb, and Pb. PSM crystallized in all stages of metasomatism. Zoning of PSM and their relationships with associated minerals (Zn-bearing silicates, tilasite, barite, carbonates, different accessory Pb-, Sb- and Zn-oxides etc.) indicate complex geochemical evolution of the ore occurrence. Possible mechanism of formation of nonsulfide parageneses of chalcophile elements is discussed.
