华南沿海地跨东南地洼区、南海地洼区和台湾地槽区。断裂构造十分发育,有北东向、北西向、东西向和南北向等四组构造系,而以北东向最为醒目,构成本区构造骨架。它控制着多阶段的地层沉积和多期次的岩浆侵入和喷出,与矿产的形成和富集关系密切,沿着区域性断裂带形成复合型断裂成矿带的特征。 South China coastal across the southeast depression, the South China Sea depression and Taiwan trough area. The fault structure is well developed and has four structural systems north to east, north west, east and west and north and south direction, while the most striking northeast is the structural skeleton of this area. It controls multi-stage stratigraphic deposition and multi-stage magmatic intrusion and discharge, closely related to the formation and enrichment of mineral deposits, and forms features of complex fracture mineralization along the regional fault zone.
