在绿岩带发展的最后阶段,岩层经受了褶皱作用、变质作用、并被侵入岩切穿,侵入岩的成分以基性侵入岩为主,在个别地带广泛发育有多相的花岗侵入岩,最早岩相是与褶皱同期的;最晚的岩相明显的切过褶皱,并被上覆的断裂破坏所控制。与晚期花岗侵入岩一起常常有稀有伟晶岩、含锡云英岩、热液脉状铜和其它有色金属矿床。但矿床规模比较小。
In the final stage of greenstone belt development, the strata underwent folds and metamorphism, which were penetrated by intrusive rocks. The composition of intrusive rocks is mainly basic intrusive rocks. In many areas, granitic intrusive rocks are widely developed. The earliest facies are contemporaneous with folds; the later facies are obviously cut-over folds and are controlled by overlying faults. Together with the late granitic intrusive rocks there are often rare pegmatites, tin-bearing dolomite, hydrothermal vein-shaped copper and other non-ferrous metal deposits. However, the size of the deposit is relatively small.
