华南地区是世界上著名的多金属矿产地，钨、锑储量占世界的50%以上，锡储量占世界的20%，还有丰富的铜、钼、铅、锌、金、银、钽、铌、重稀土、铀等资源。本专刊报道了华南地区构造演化、岩浆活动和矿床研究的最新进展，使人们对中生代大规模岩浆活动和成矿事件有了更全面的认识：（1）华南地区自古生代以来处于多次俯冲的弧后环境，可能对成矿物质的预富集有贡献; (2)太平洋板块俯冲是控制华南晚中生代大规模岩浆作用和成矿作用的主要因素，主要表现为平面俯冲、山脊俯冲/板片撕裂和板片回滚。
South China is famous for its polymetallic deposits, with more than 50% of the world's W and Sb reserves and 20% of the Sn reserves, as well as abundant Cu–Mo–Pb–Zn–Au–Ag, Ta, Nb, HREE and U. This special issue reports recent progress on the tectonic evolution, magmatism and ore deposits of South China, which leads to a more comprehensive understanding of the Mesozoic large scale magmatism and mineralization events: (1) South China has been located in backarc settings during multiple subductions since the Paleozoic, which may have contributed to pre-enrichments of the ore-forming materials. (2) The Pacific plate subduction was a principle factor that controlled the late Mesozoic large scale magmatism and mineralization in South China, through flat subduction, ridge subduction/slab tearing and slab rollbacks.
