The global tectonomagmatic process of the forma tion of the oceanic crust in mid oceanic ridges and its movement from the spreading axis is accompanied with the formation of hydrothermal systems above magmatic chambers. The waterrock interaction is the major process providing mineralization of fluids as they migrate through the newly formed oceanic crust. The solutions are ultimately discharged at the bottom to form hydrothermal ore edifices and metalliferous sediments. Subsea hydrothermal vents known in the mid oceanic ridges overlapped by sediments and with out sediments differ from each other in the fluid com position.
