- Type
- Massive veinlets and fibrous quartz veins with stibnite
Massive stibnite veinlet with pyrite crystals, and antimony-bearing fibrous quartz veinlet; the least radiogenic stibnites of the study (206Pb/204Pb 17.965-18.037). 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).
