摘要:

从现代块状硫化物矿床成矿特征对比角度,总结分析了世界现代海底喷流的块状硫化物成矿堆积,综述了现代海底块状硫化物成矿主要形成于洋壳和岛弧环境的实际观察结果,突出强调了洋壳环境和岛弧或陆壳环境两种成矿环境对成矿类型分类的意义。对上地幔部分熔融岩浆来源与地壳物质可能带入、火山喷发岩浆系列的演化和对热液成矿作用的控制进行了讨论,对比分析了岩浆流体对成矿的重要贡献和控制作用,以及成矿热液循环体系形成的条件和模式。

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.
