A genetic variety and convergence of epithermal gold-silver mineralization

The changing of mineral and geochemical paragenesis in ores corresponding to the correlation between epithermal vein deposits and ore-formation series is investigated. The established convergent character of various epithermal gold-silver mineralization is, as shown, determined by their similar physico-chemical ore-formation conditions. Thus, within Pacific-Ocean tectono-magmatic belt and in the conjoint structures epithermal gold-silver mineralization is especially widely distributed in accordance with the zones of disseminated and vein gold-sulfide and gold-quartz ores, in the region of copper-molybdenum-porphyric and pyrite ore assemblies as well as basic-ultrabasic complexes (gold-silver-telluride deposits), and also, to lower degree, in association with iron quartzite deposits.
