目前公认的两个太古代基本岩石组合是花岗岩-绿岩和高级片麻岩。由于绿岩带不仅在地壳的早期形成和演化上具独特意义,而且蕴藏有极为丰富的金、铜、铁和镍等矿产,因此引起我国广大地质工作者的极大注意。我国太古代变质杂岩,很可能大部分都与高级片麻岩组合类似,而 Currently recognized two basic Archean rock assemblages are granite - greenstone and advanced gneiss. Because greenstone belt is not only of unique significance in the early formation and evolution of the crust, but also contains extremely rich minerals such as gold, copper, iron and nickel, it has attracted great attention of the majority of geological workers in our country. Most of the Archean metamorphic complexes in our country are likely to be similar to the high gneiss assemblages
