摘　　要：华南地区成矿地质构造环境经历了六个地质构造演化阶段,并在中生代形成了长江中下游、江南隆起、赣东北(钦杭带东段)、武夷-云开、南岭和东南沿海6个构造岩浆成矿带。本文依矿床的成矿系列理论,将华南中生代繁多的矿床,按地质构造单元及环境、岩浆成矿作用的专属性、有成因联系的矿床组合,划分出五个矿床成矿系列,总结了各矿床成矿系列的特征,分析了各矿床成矿系列的边界及部分过渡、重叠的特色。本文总结了华南成矿作用的时空分布及演化规律,分析各矿床成矿系列与壳幔作用的关系,探讨了华南中生代成矿作用与印支期华北、扬子板块碰撞对接、燕山期古太平洋板块向欧亚板块俯冲之远程影响的关系,以及华南地区燕山期地幔活动对该区岩浆成矿作用的重要贡献。South China underwent six stages of tectonic evolution and formed favorable metallogenic geological environments, the Mesozoic in particular, within which six tectonic magmatic belts can be concluded： the Middle and Lower Reaches of the Yangtze River, the Jiangnan Uplift, the Northeast Jiangxi （the eastern Qin-Hang belt）, the Wuyi-Yunkai, the Nanling and Coastal Areas of Southeast China. According to geological tectonic units and environments, metallogenic specialization of the magmatism, closely genetically related deposits, the deposits formed in the Mesozoic in South China have been divided into five metallogenic series. The characteristics of each metallogenic series have been summarized, and the boundary and transition or overlapping features of these metallogenic series have also been analyzed. On this basis, the spatial-temporal distribution and evolution, the relationship between each metallogenic series and crust-mantle interaction, the relationship between the mineralization in Mesozoic and the collision between the North China and the Yangtze Plates in Indosinian, the remote effects of the Paleo-Pacific Plate subduction underneath the Eurasian Plate in Yanshanian, and important contributions of the mantle tectonic movement in Yanshanian to magmatic mineralization in South China, etc., have been discussed in this paper.
