(Stříbro, Plzeňský Kraj)
Located about 25 km west of Plzeň.
Hydrothermal Pb(-Zn) vein deposit exploited from 12th century. Veins in Upper Proterozoic metamorphic rocks. More than 50 mineralized veins are known, max. length 2.4 km and up to 50 cm thick (extremes over 3 m). Mineralization is very simple - mainly quartz, minor baryte and carbonates, ore minerals are galena and sphalerite, pyrite with marcasite, rare chalcopyrite and arsenopyrite.
Well known is the oxidation zone, which goes about 130 m deep. The most interesting were two generations of abundant cerussite crystals up to 5 cm large (described by J. T. Lindacker in 1791). Pyromorphite is known as green, brown or gray hexagonal crystals and also as an interesting calcium-rich variety, which was desribed as a new mineral "miesite" (botryoidal gray aggregates). Part of the lead is substituted by max. 9 % CaO.
