摘　　要：通过对矿床成矿系列30多年的长期研究,认为华南是我国与中生代岩浆岩有关有色、稀土、稀有金属、铀等矿床成矿系列发育最完善的成矿省之一,并且形成了以武夷-云开构造-岩浆-成矿带为中心、向东、西两侧对称分布、成岩成矿时代逐渐变年轻的区域性分带格局。这样的分带格局受到了区域性水平方向构造运动和垂直方向壳幔物质相互作用的共同制约,而壳幔相互作用程度的不同和表壳构造的差异也是华南出现不同成矿系列(亚系列)以及成矿系列叠合的重要原因。Based on the study of metallogenic series with a history of more than 30 years, this paper points out that South China is one of the most important metallogenie provinces in China, with plentiful nonferrous, rare earth ele-ments, rare metals, and uranium mineral resources related to Mesozoic magmatism. In this region, with the Wuyi-Yunkai tectonic-magmatic-metallogenic belt being the axis, a huge zoning pattern covering an area of more than 50×10^4 km2can be recognized, where the ages of magmatism and mineralization become younger towards either wing. The regional zoning of mineralization in South China was controlled not only by horizontally movement of plate but also by vertically movement of materials from crust and mantle.
