Makovickyite
Makovickyite is an IMA-recognized mineral species in the sulfosalt class, with the chemical formula Cu₁.₁₂Ag₀.₈₁Pb₀.₂₇Bi₅.₃₅S₉.
It crystallizes in the monoclinic crystal system (space group C2/m). It is a member of the Pavonite structural group.
Key properties: Metallic luster.
IMA symbol Mvk, IMA status: approved, named in 1986.
Among other bismuth-bearing sulfosalts in a dolomite skarn (Băiţa, Romania); in a hydrothermal tungsten deposit in amphibolites and felsic gneisses, in discordant quartz veins (Felbertal mine, Austria).
It is found associated with Chalcopyrite, hammarite, bismuthinite, krupkaite–lindströmite, tetradymite, wittichenite, paděrite, miharaite, bismuth, gold, scheelite, molybdenite, galena.
The mineral was named to honor Professor Emil Makovicky (1941–), Slovak–Danish mineralogist, University of Copenhagen, Copenhagen, Denmark.
