Abstract (in english)
   Rare occurrences of Sn-minerals (cassiterite, stannite), Bi-minerals (native bismuth, hedleyite, gustavite-lillianite, secondary Ag-wittichenite and bismuthite) and Ag-minerals (gustavite-lillianite, hessite, Ag-rich galena and secondary Ag-wittichenite and acanthite) were newly described from the pegmatite, aplite and quartz veins of the Žulová massif. These minerals come from "Haspelberg" at Vápenná, Stará Červená Voda and Nadziejow-Kamienna Góra localities. Very pure cassiterite represent pegmatite stage of the mineralisation, eventually transition between pegmatite and high-temperature hydrothermal processes (pneumatolytic stage). Other described minerals - stannite, gustavite-lillinatite and Ag-rich galena with Bi inclusions belong to high-temperature hydrothermal assemblage with temperatures of crystallization between 370-550°C. The latter hydrothermal assemblage siderite-hedleyite-native bismuth-hessite crystallized at temperatures lower than 270°C.
   However, the described mineral assemblages as well as the increased concentrations of Sn, Bi, Ag and Cd in common sulphides (chalcopyrite, pyrrhotite, galena and sphalerite) and frequent occurrence of molybdenite display chemical composition of postmagmatic hydrothermal solutions derived from the Žulová granitic massif. From the metalogenetical point of wiev, the high-temeprature hydrothermal occurrences of ore-minerals from the pegmatites, aplites and quartz veins of the Žulová massif form a distinct metalogenetical group in the territory at the boundary of Silesicum and Lugicum, defined by unique mineral assemblages and their chemistry
