- Аннотация: The formation of volcanic-hosted massive sulfide (VMS) deposits of Urals is related to shallow chambers of acidic magma. Melt inclusions of felsic rocks (rhyolite-basalt bimodal complex) correspond to tholeiitic series compositions. For the Uzelginsk ore field LA-ICP-MS analyses of inclusions of magmatic fluid and melt in quartz phenocrysts reveal high concentrations of metals (Cu, Zn, Au etc.). Magmatic vapour was enriched with Cu, Se and Au relative to coexisting melt.
