对于众所周知的多样和多相冒地槽金矿床来说,具有代表性的金矿化是两阶段的和不常见的三阶段共同矿化。本文要研究的则是更复杂的对象。在这个对象里显示了过去未曾注意的以地幔物质参加和以风化壳线性成分有规律形成为条件的成矿阶段。该对象位于地壳硅铝质块地(玄武岩层的厚度小于30公里)(见图1),由含玄武岩成 For the well-known diverse and heterogeneous mammoth gold deposits, representative gold mineralization is a two-phase and uncommon three-phase co-mineralization. This article is to study more complex objects. This object shows the previously unknown metallogenic stages of the mantle material and the regular formation of the linear components of the weathering crust. The object is located in the crustal Si-Al block (basalt thickness of less than 30 km) (see Figure 1), from basaltic
