| 摘要: |
中国南方碳酸盐台地从震旦纪到志留纪十分发育,它对认识中国南方沉积地壳演化和油气勘探具有重要意义。90年代以来,中国南方碳酸盐台地从台地内部结构研究发展到对碳酸盐台地边缘、台地几何形态、台地边缘形态的研究,并把它们的形成和演化与大地构造、全球海平面变化、沉积层序、动力演化过程结合起来,进行碳酸盐台地发展、演化、沉降、生长的定量模拟。此外,还特别重视重大地质事件和非现实主义沉积作用探索。
中国南方早古生代碳酸盐台地,随着扬子板块的裂谷拉张、被动大陆边缘构造热沉降和前陆挠曲,经历了碳酸盐台地产生、发展和消亡的完整威尔逊旋回动力演化。最终这个巨大的碳酸盐台地因挠曲沉降淹没和大量碎屑岩覆盖而消亡,是具有非常良好远景的油气资源探区。 |

| Abstract: |
| The Early Palaeozoic carbonate platform in southern China shows a long and complex history with a complete dynamic evolution of the Welson cycle,spanning the initiation,development and termination due to extensional rifting of the Yangtze plate,tectonic thermal subsidence of the passive continental margins,and foreland warping. This huge carbonate platform was finally died and buried by thick piles of siliciclastic rocks trom the Cathaysian plate,and now is interpreted as a potential area for the prospecting and exploration of oil and gas resources. |
