The four dynamic factors are related to and interact with each other; and the mantle-crust interaction leads to the regular time-space zonation of endogenetic deposits on a regional scale. The Meso-Cenozoic mineralization pattern in China can be outlined as the network tectono-metallogenic pattern constructed by NNE- and E-W-trending tectonics in eastern China, and multi-layer ring tectono-metallogenic pattern in the Qinghai-Tibet plateau and its northern and eastern neighbouring areas.展开更多
