Abstract

Plate-tectonic paleogeodynamic setting of volcanic massive sulfide-bearing complexes of the Magnitogorsk island-arc megazone was reonstructed based on petrological-geochemical study and available geophysical data. The correlation between La/Yb ratio, Th, Yb, TiO2, and Zr concentrations in the basalts of ore regions, and ore volumes (Cu + Zn, in kt) in volcanic massive sulfide deposits was established. This indicates that the ore compositions and volumes in the ore-magmatic systems depend on the melting degree of suprasubduction mantle wedge. It was concluded that supraduction asthenospheric diapirs participated in the genesis of massive sulfide-bearing complexes. The obtained information can be used to predict new areas promising for massive sulfide mineralization.
