| 摘 要： | 成矿演化可以分成５个时期（Ｍａ）：（１）小岩石圈板块，褶皱作用期并发育绿岩带（３８００～３０００）；（２）陆壳主块的形成（３０００～２７００）；（３）初始超大陆，开始板块构造作用的影响（２７００～１８００）；（４）原生陆壳的多重作用（１８００～６００）；（５）深部地幔分异，以构造岩浆分异作用为主（６００～０）。

| Abstract: | The evolutionary metallogeny may be divided into 5 periods(Ma):(1) Finelithosphere plates. Epochs of folding and development of greenstone belts (3800～3000);(2)Formation of the main bulk of the continental crust(3000～2700);(3) First supercon-tinents. Beginning of the action of the plate tectonics mechanism(2700～1800);(4)Multi-ple processing of the primary continental crust(1800～600);(5) Deep mantle differentia-tion,domination of the processes of tectonomagmatic differentiation(600～0). |
