BISMUTH SULFOSALTS OF THE CUPROBISMUTITE, PAVONITE AND AIKINITE SERIES FROM THE ROZÁLIA MINE, HODRUŠA–HÁMRE, SLOVAKIA

An interesting association of the Bi sulfosalts was identified in the Rozalia mine, Hodrusa–Hamre, 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 Rozalia mine. Kupcikite has the structural formula (Cu 6.73 Fe 1.10 ) ∑7.83 (Bi 9.49 As 0.36 Ag 0.24 ) ∑10.09 (S 18.89 Se 0.13 ) ∑19.02 ; that of hodrusite is (Cu 7.69 Fe 0.38 ) ∑8.07 (Bi 11.22 As 0.34 Ag 0.53 ) ∑12.09 (S 21.99 Se 0.17 ) ∑22.16 , and that of cuprobismutite is (Cu 7.47 Fe 0.14 ) ∑7.61 (Bi 12.81 As 0.69 Ag 1.38 ) ∑14.88 (S 23.85 Se 0.22 ) ∑24.07 . Makovickyite has the structural formula Cu 1.14 Ag 0,99 Pb 0.13 Bi 5.07 S 8.94 Se 0.06 ; that of pavonite is Cu 0.43 Ag 0.82 Fe 0.03 Pb 0.19 Bi 2.84 S 4.96 Se 0.04 , that of dantopaite is Cu 2.29 Ag 3.68 Fe 0.12 Pb 1.32 Bi 12.02 S 21.85 Se 0.15 , that of benjaminite is Cu 1.13 Ag 2.26 Fe 0.16 Pb 0.76 Bi 6.51 S 11.91 Se 0.09, and that of mummeite is Cu 1.44 Ag 2.61 Fe 0.41 Pb 0.95 Bi 6.70 S 12.93 Se 0.07 . The associated sulfosalts are paděraite, berryite and members of the bismuthinite–aikinite series (bismuthinite, gladite, krupkaite, lindstromite, friedrichite and aikinite).
