Abstract:
It is summarized and analyzed that massive sulfide accumulations of the modern seafloor in the world from their contrasting of the minerogenetic characteristics, and outlined that the result of actual observation of the massive sulfides of oceanic crust and island arc at the modern seafloor, especially emphasized significance of two kinds of minerogenetic environments(oceanic crust and island arc or continental extension)for classification of minerogenetic types. Also, it is discussed that magmatic origin of upper mantle partial melting and possible contaminate of crustal compositions and magmatic evolution of volcanic eruptions control hydrothermal mineralization, and analyzed that important contribution and control action of a magmatic fluid to a hydrothermal mineralization and formation conditions and models of a circulation system of hydrothermal mineralization.
