<abstract xmlns="http://www.w3.org/1999/xhtml">Linarite, PbCu2+(SO4)(OH)2, and associated minerals were studied at new locality near Kletné, where they occur in dump material of historic Ag-Pb mines exploited during the 16th century. Linarite forms thin blue coatings and tiny dark blue crystals (&lt;1 mm in size) in small cavities, in assemblage with cerussite, brochantite and supergene copper sulfides. Mineral was identified by chemical analyses (electron microprobe), Raman spectroscopy and powder X-ray diffraction analysis. Chemical composition of the studied linarite can be expressed by empirical formula Pb0.98Cu1.06(SO4)Σ0.96(OH)2.15 and its refined unit-cell parameters are: a = 9.6944(3), b = 5.6499(2), c = 4.6846(1) Å, ß = 102.669(3)° and V = 250.50(1) Å3. Linarite formed together with other supergene minerals in the oxidation zone of the deposit by weathering of Pb- and Cu-sulphides.</abstract>
