| 摘 要： | 通过对华南扬子陆块和华夏增生体两大构造单元南华纪-二叠纪7条综合性剖面岩性、岩相、地层厚度、沉积环境、变形与变质作用的对比研究, 以及对扬子陆块南缘以及华夏增生体具有指相意义(与洋壳相关)的岩石组合的系统总结与分析, 以地层区和分区为单位对盆地原型进行了初步划分, 在此基础上讨论了华南地区南华纪-二叠纪盆地和构造演化的基本规律, 总结出构造演化的发展阶段, 揭示了扬子陆块与华夏增生体沿江绍-郴州-钦防北东段碰撞对接的时间发生在早古生代末, 西南段碰撞对接的时间相对较晚, 可能发生在二叠纪末.

Sedimentary and Tectonic Evolution of Nanhuan-Permian in South China |
| |
| Abstract: | This paper firstly analyzes the lithological features, the thickness of sequence, metamorphical features and the sedimentary environment of seven Nanhuan-Permian combined sections from South China, then analyzes the petrological assemblages including ophiolites, basalts, island arc igneous and the TTG-GG suites (granites) from the area of south margin of Yangtze continental block and the area of Cathay accreting block and lastly analyzes the basin features based on the lithology of each unit (formation) from South China. Based on the above-mentioned analyses, four stages of tectonic evolution of South China are identified and it is concluded that the collision between the Yangtze continental block and Cathay accreting block occurred at the end of the Early Paleozoic along the northeastern part and the collision along the southwestern part occurred at the end of the Permian. |
