Abstract
The basis of the work is the postulate of V. I. Smirnov that the metallogeny of the ocean is determined by basaltoid magmatism. The morphotectonics and geodynamic position of the structures of the World Ocean, the evolution of which was accompanied by the outpouring of basalt lavas to the bottom and their interaction with ocean water and ocean biota, were characterized by the analysis of multi-scale geological and geophysical date. Two categories of global morphostructures are identified as potential sources of endogenic and ore matter: the first are genetically related to the accretion of the lithosphere at the boundaries of plate separation, the second – with intraplate volcanic-tectonic processes. Comparative estimates of the scale of the substance intake for the two categories have been carried out and it is shown that they may differ slightly or be close.
