Trepca complex
42.9392° N, 20.9181° E · ± 1 km
Galena, Marcasite, Pyrite, Pyrrhotite, Quartz, Rhodochrosite and Siderite from Mitrovica District, Kosovo, with photos of specimens from this locality.
Minerals found here
On the same specimen
Trepca specimens are shown that consist mainly of galena with slender quartz prisms, some with a small cluster of quartz prisms; the captions do not say which mineral grew first.
Slender quartz prisms combined with galena illustrate the sulfide and quartz vein assemblage of this famous ore belt.

1 specimen photo(s) from this locality show marcasite with barite together. The pairing comes from the photographer's file name and label, so the relationship between the two minerals is not specified.
2 specimen photo(s) from this locality show siderite with pyrite together. The pairing comes from the photographer's file name and label, so the relationship between the two minerals is not specified.
1 specimen photo(s) from this locality show pyrrhotite with sphalerite together. The pairing comes from the photographer's file name and label, so the relationship between the two minerals is not specified.

- History
- Lead-silver mining here predates the Romans and intensified from 1303; Trepca Mines Ltd was formed in 1927 with production from 1930, and total output is estimated at about 32 million tonnes. Specimens shown by one author were collected around 1959 from ledges where miners had left crystal clusters.
