| 摘 要： | 中南部非洲优势矿产资源有金、铜、铁、铬、金刚石,锰、铀、镍、钒、钴、铂、锑的储量也居世界前列。主要的矿产集中分布于前寒武纪地体内,中南部非洲前寒武纪地体的形成演化决定了矿产的种类和主要成矿类型。文章总结了中南部非洲的地质构造演化以及其主要矿产资源的成矿类型和分布规律,并划分成矿区带至三级。探讨了部分主要成矿区带的成矿规律:太古宙的矿产主要与花岗-绿岩地体有关;古元古代的矿产主要分布于陆缘盆地,与岩浆作用有关;中元古代的矿产主要与岩浆作用有关,次为沉积变质作用;新元古代的矿产主要与沉积变质作用有关,次为岩浆作用。

| Abstract: | Superior mineral resources in central south Africa are Au, Cu, Fe, Cr, diamond, Mn, U, Ni, V, Co, PGE and Sb. Reserves of the mineral resources are top-ranked worldwide. They occur mainly in the Pre-Cambrian terrains. Formation and evolution of the terrains are key factors for what mineral resources and what kinds of ore deposits occur within them. In this paper are summarized geo-tectonic evolution and distribution pattern of mineral resources then metallogenic belt III is lineated in the central south Africa. Metallogenic pattern of some ore belts is discussed. Archean mineral resources are mainly related to granitoid-green stone terrains; Palaeo-proterozoic mineral resources distributed in basins at continental margins and related to magmatism; the Middle Proterozoic mineral resources mainly to magmatism then sedimentary metamorphism; Neo-proterozoic mineral resources mainly to sedimentary metamorphism then magmatism. |
