| 摘 要： | 本区成矿地质条件优越，矿产丰富多彩。目前已找到116种矿产，探明矿床数百个，已涌现出像大宝山、矾口、大降坪、211、河台、石碌、羊角岭等为代表的一大批大型、超大型矿床。然而，大多数矿床有各自的特色，又有相互的空间和成因联系，构成成矿系列。区内可划分为4个成矿区带，22个成矿系列、亚系列。南岭成矿带以壳源和壳慢源岩浆成矿系列为主；云开成矿带以壳幔源岩浆和沉积变质成矿系列为主；沿海成矿带以陆相表生风化带和壳幔源岩浆成矿系列为主；海南成矿区以沉积变质火山热液成矿系列为主。这些成矿区带成矿系列具有独特的演化规律，即成矿区带矿化随时空演化规律、成矿系列随构造应力场演化规律和成矿系列随岩浆序列演化规律。

| Abstract: | In Guangdong and Hainan provinces, there are excellent geological conditions favorable for mineralization and therefore extremely important reserve and abundant types of mineral resources have been found. A total of 116 mineral commodities has been discovered and several hundred deposits have been targeted including the large and superlarge ones like Dabaoshan, Fankou, Dajiangping, 211, Hetai, Yangjiaoling and Shilu. Though they have their own characteristics, these ore deposits occurred in groups and are genehcally related to each other. Four metallogenetic belts/province are dishnguished. In the Naming metallogenetic belt the main metallogenetic series are commonly associated with crust/mantle-derived magmas. The Yunkai metallogenetic belt is mainly characterized by the mineralization related to crust/mantle magmatism and metamorphism. The weathering mineral deposits become important in the coastal metallogenetic belt. By contrast hydrothermal process played an important role in the formation of the Hainan metallogenetic province. These metallogenetic belts or province have distinct evolutionary regularities. It is demonstrated that the evolution of metallogenetic series can be traced in space and time, and is related to evolution of regional tectonic regimes and magmatism. |
