在这里将对出现在浅变质的太古代地区的金属矿床作一总结,特别值得注意的是,这些矿床的产状是受地层控制的。在不同地盾区的矿床类型是十分相似的。任何一个具体的矿种都局限在一定环境中,任何金属矿床形成的成矿作用都可能与绿岩带的发育及其花岗岩有关,正如在达瓦尔克拉通的情况一样。绿岩带含有大批有经济意义的矿产,是世界上Au、Ag、Cr、Ni、Cu和Zn等元素的主要产地。在过去,绿岩带被称为金矿带。
Here, we will summarize the metal deposits appearing in the super-metamorphic Archean area. What is particularly notable is that the occurrence of these deposits is controlled by the strata. The deposit types in different shield areas are very similar. Any specific mineral is confined to a certain environment. The metallogenesis of any metal deposit may be related to the development of the greenstone belt and its granite, as is the case in Davalcorton. Greenstone belt contains a large number of economically valuable minerals, is the world’s main origin of Au, Ag, Cr, Ni, Cu and Zn and other elements. In the past, greenstone belt is known as the gold belt.
