Hydrothermal Au mineralization is controlled by subduction-related gabbro-tonalite-granodiorite-granite (GTGG) complexes. They form 3 time lags: 400-380, 365-355 and 320-290 Ma. All GTGG complexes have a mantle-crustal origin. The main petrogenic process is a multistage anatexis. The main part of tonalities and granodiorites are the products of hornblende gabbro partial melting and the granites, for their turn, are the result of granodiorite re-melting. Gold concentrations decrease in such anatectic rock series but increase in equilibrium fluid. So, the gold mineralization is closely connected with the last portions of magmatic rocks.
