| 摘 要： | 在研究全球不同地区二叠纪沉积、层序及生物资料基础上，通过全球诸大陆典型剖面层序划分和对比表明，二叠纪至少有６次海平面升降事件具全球对比意义。二叠纪全球海平面旋回曲线，在不同板块不同成因盆地，其形态及结构不同，但总体可分为两种类型或分支：一是以海相→陆相沉积序列为主的反映主体海平面下降的经典型或欧美型；二是以海相碳酸盐岩→碳酸盐－硅质岩沉积序列为特征的揭示主体海平面上升的特拉斯型或华南型。这与二叠纪特定的全球构造－古地理密切相关。

| Abstract: | The authors in this paper suggest,based on the previous date of Permian sediments,sequences and biostratigraphy in conjunction with worldwide sequence division and correlation,that there are at least six eustatic sea level events during the Permian which can be traced or correlated all over the world.Generally speaking,the Permian parts of Phanerozoic eustatic sea level cycle curves include two patterns or branches:the one is the so called classical or Euramerican type which represents the overall sea level fall characteristic of marine nonmarine regressive successions,the other is defined as the Tethyan or South China type which points to the overall sea level rise characteristic of transgressive carbonate rock or carbonate siliceous rock successions.The eustatic sea level curves mentioned above are closely related to the global tectonic and palaeogeographic frameworks. |
