Abstract
During the last years, several large complex antimony deposits (Sb-Pb/Zn-As association) have been discovered in Yugoslavia. One of these deposits is Rujevac in western Serbia. Genetically related to the Tertiary granodioritic magma, the mineral parageneses are characterized by some specific features. So, pyrite displays occasionally a zonal pattern of arsenic distribution: the marginal zones contain up to 6 wt% of As. Besides common galena, antimoniferous galena containing up to 10. 5% of Sb is known. Among lead sulphantimonides, some new species are indicated. The paragenetic sequence of the Pb-Sb-S minerals indicates that the fluctuations in the chemical potential of Sb2S3, influenced by the presence of lead and antimony in the ore-bearing hydrothermal solutions, and geochemistry of the deposit, were such that they resulted in formation of an order of deposition like stibnite → lead sulphantimonides → galena. This order of crystallization seems to be characteristic of some complex Sb-Pb-S ores.
