Abstract

An interesting association of the Bi sulfosalts was identified in the Rozália mine, Hodruša–Hámre, Slovakia. Sulfosalts of the cuprobismutite series are the most common, and occur in paragenesis with other Bi sulfosalts, chalcopyrite and hematite. Members of the pavonite homologous series are associated with bismuthinite derivatives and quartz of the amethyst variety. Three members of the cuprobismutite homologous series and four members of the pavonite homologous series have been found in a hydrothermal base-metal mineralization in the Rozália mine. Kupčíkite has the structural formula (Cu6.73Fe1.10)∑7.83 (Bi9.49As0.36Ag0.24)∑10.09(S18.89Se0.13)∑19.02; that of hodrušite is (Cu7.69Fe0.38)∑8.07(Bi11.22As0.34Ag0.53)∑12.09(S21.99Se0.17)∑22.16, and that of cuprobismutite is (Cu7.47Fe0.14)∑7.61(Bi12.81As0.69Ag1.38)∑14.88(S23.85Se0.22)∑24.07. Makovickyite has the structural formula Cu1.14Ag0,99Pb0.13Bi5.07S8.94Se0.06; that of pavonite is Cu0.43Ag0.82Fe0.03Pb0.19Bi2.84S4.96Se0.04, that of dantopaite is Cu2.29Ag3.68 Fe0.12Pb1.32Bi12.02S21.85Se0.15, that of benjaminite is Cu1.13Ag2.26Fe0.16Pb0.76Bi6.51S11.91Se0.09, and that of mummeite is Cu1.44 Ag2.61Fe0.41Pb0.95Bi6.70S12.93Se0.07. The associated sulfosalts are paděraite, berryite and members of the bismuthinite–aikinite series (bismuthinite, gladite, krupkaite, lindströmite, friedrichite and aikinite).
