Abstract - Summary 
(short description):
Quartz-sulphide-wolframite veins are located in the intrusion of granite-porphyrs C3 and genetic are connected with more deep-seated rare-metal leucocratic granites P1. The veins are accompanied by greisens, consisting of zinnwaldite, quartz, feldspar, topaz, sericite, fluorite, caronates Fe-Mn-Ca. Leading (paragenetic) mineral associations of the veins are: quartz-cassiterite- wolframite with triplite, zinnwaldite (T of homogeneousness of quartz is 275-330ºŃ) and quartz-carbonate-sulphide with sphalerite, chalcopyrite, galenite, bismuthine and others (T of homogeneousness of quartz is 200-240ºŃ). The composition of fluids of gas-liquid inclusions is sodium-calcium-chloride-carbonic acid. The formation minerals of intermediate composition in isomorphic series of group zinnwaldite, hubnerite-ferberite, sulfo-stannates Cu and Zn is typical. By isotope data the lead of galenite has Cambrian age, sulphur of sulphides is not mantle (δ 34S – 5,6 ‰), O and C of vein carbonates are magmatic origin (δ 13C – 4,3 and 3,1 ‰, δ 18O – 4,7 and 7,8 ‰)
