SPECIFIC FEATURES OF MASSIVE SULFIDE ORE FORMATION UNDER SUBMARINE CONDITIONS AT VARIOUS DEPTHS

Abstract

The viewpoint that the formation of massive sulfide ores of the Urals on the bottom of water basins is due to the activity of shallow-seated magma chambers has predominated over the past few decades. However, if we take into account recent developments in modeling of the physicochemical evolution of endogenic fluids, including the concept of “sulfur intercept” in sulfide ore formation, the conventional genetic model illustrates only a particular case of massive sulfide ore formation. As will be shown below, extrapolation of this model to all cases is methodically incorrect because of the omission of near-vertical metasomatic massive sulfide bodies.
