Spinel- and Högbomite-Supergroup Minerals from Sulfide-Free Endogenic Pb–Zn–Sb–As Assemblage in the Pelagonian Massif, Republic of North Macedonia

Abstract

Sulfide-free mineral assemblages with the chalcophile element minerals from occurrences associated with altered rocks of Pelagonian massif, Republic of North Macedonia have been studied. The inputting sequence of various ore-forming constituents has been revealed on the basis of morphological features, zoning of the spinel-group minerals, and the högbomite supergroup minerals. Conclusions about the inputting consequences of various ore-forming components have shown that these minerals easily form epitaxial and syntaxial intergrowths with each other and with nežilovite due to commensurable unit cell parameters. Some potentially new minerals were identified belonging to the högbomite supergroup.
