- Siderite-quartz Pb-Zn vein and quartz veinlets with Sb sulfosalts
Siderite-quartz vein with Pb-Zn sulfides (galena 18.168-18.176) cut by fibrous quartz veinlets with stibnite, zinkenite and plagionite that are more radiogenic (18.250-18.288). 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.
