Systems of differential equations,r with the deposits of greenstone belts and some others, are classified as the deposits connected with ore-bearing volcanic-intrusive complexes of intercontinental rift zones. Massive sulfide ores, sulfide-bearing intrusions, and ultramafic volcanites are shown to have been formed as the result of s

In the regional metamorphic stage, epigenetic ores appear that are distinguished by diversities in mineral composition, typical of the specific tectonic zones formed during such metamorphism.

The probable values of the physicochemical parameters of copper- and molybdenum-bearing hydrothermal solutions are estimated on the basis of calculations and experimental data.
