Other hydrothermalPb-Zn-Fe (Sb)
- Type
- Siderite-Pb-Zn veins overprinted by Sb sulfosalts
Siderite ore with Pb-Zn sulfides replaced by Pb-rich sulfosalts (boulangerite, meneghinite) that inherit galena lead (206Pb/204Pb 18.210-18.223). Pb from Wagner and Schneider (2002): late-Variscan mesothermal antimony mineralisation, either as quartz-stibnite veins (fibrous quartz, stibnite and Pb-Sb sulfosalts) or as Cu-Pb-Sb sulfosalts replacing earlier Pb-Zn veins. Coordinates not published (schematic map only).
