| 中文摘要:胶东和滇黔桂是我国两个典型的金矿集中区，它们在成矿特征和矿床成因上各不相同，但作为金矿集中区，它们可能都受到地幔柱构造的制约或影响，金可能都主要来自于深部或者来自于地幔柱头部，而容矿围岩的差别只是一个金的“捕集器”的不同而已。另外，胶东地幔柱演化较成熟，地壳物质剥蚀更强烈，因而大型金矿出露较多；而滇黔桂地区剥蚀相当弱，深部可能存在更大规模的金矿。 |

| Controlling Effects of the Mantle Plume on the Jiaodong and Dian-Qian-Gui Gold-concentration Areas |

| Abstract:The Jiaodong area in Shandong province and the DianQianGui area located in the Yunnan-Guizhou-Guangxi border region are two important gold concentration area s in China. Although the two areas are different in host rocks of gold deposits, mineralization characteristics and genesis, they might have been subjected to t he control or influence of the mantle plume. Gold might be mainly derived from the deep source or from the top of the mantle plume, while the host rocks only played a role of “traps”of gold. In the Jiaodong area, because the mantle plum e has evolved into a mature stage, the upper part of the crust has been eroded a way and granite sills appear at the surface. So, the gold dep osits associated with granites are easy to discover. By contrast, the granites in the Dian-Qian-Gui area are buried deeper than those in Jiaodong, so gold depo sits are difficult to find, but the gold prospects there may be better than in Jiaodong as much larger gold deposits might exist at depths. |
