| Abstract: | Relationships of gold mineralization to deep-seated low-density domains of granitization are considered. The gold mineralization originates in the zones of interaction of these domains with femic rocks established from the results of regional magnetic survey or with thick folded sequences of carbonaceous clay rocks and intercalated members of femic volcanics. The intensity of granitization decreases from continent to ocean, and the ore-forming centers and mineralization are rejuvenated in this direction from the Jurassic-Cretaceous to the Pleistocene, while the productivity of the ore-forming process remains unchanged. |
