| 中文摘要: |
| 金矿密集的胶北隆起区是一个独立的地体,具有典型的早前寒武克拉通的一系列特征。目前没有资料表明胶东群和花岗岩能为胶北大型或中型的金矿床提供足够的成矿物质。而从胶北地体构造环境的研究表明,从克拉通周边高级和高压变质带以及下行的板块和板片大量转移出来的成矿物质到克拉通内部,形成了许多重要的金矿床和成矿带。 |
| 英文摘要: |
| The Jiaobei uplifted block clustered with numerous gold deposits is an independent terrane, which is separated from the Luxi terrane by the Danlu fault to the west, from the Liannan terrane by the Pingdu-Laixi fault to the south, from the Jiaodongnan-Sudongbei-Huanghai terrane by the Rongcheng-Haizhou eclogite belt to the east. The Jiaobei terrane is a typical Precambrian craton, which exhibits a series of characteristics. Similarities to the southern Africa and the Zimbabwe cratons are obvious, particularly in the development of a circum-cratonic high-grade metamorphic mobile belt along the boundary faults. The main differences of this terrane from the southern Africa craton are recognized in its intense Mesozoic tectonism and magmatism. |
