| 摘 要： | 总结各类沉积盆地的沉积和地层格架，厘定出６类等时性地层界面和５个级别的成因地层单位，在分析地层界面性质和各类成因地层单位沉积构成的基础上，将华南二叠－三叠系划分为７个沉积幕、３个构造沉积幕和２个沉积盆地域、恢复了华南板块二叠－三叠纪的演化过程，论述了板块构造运动，海平面升降和源区侵蚀作用对各级成因地层单位的控制意义，证明了华南的古特提斯海经历了陆表海和伸展裂谷海两个演化阶段。

| Abstract: | Gether up the depositional and stratigraphic framework of different basins, six types of the chronostratigraphic interface and five orders of the genetic stratigraphic units are defined. On the basis of analysis for the character of stratigraphic interface and the depositional architecture of genetic stratigraphic units, the stratigraphic sequence of Permian to Trassic is divided into seven depositional episodes, three tectono-depositional episodes and two sedimentary basin tracts, and the evolutional course of South China Plate is recovered during Permian to Trassic period. This paper also deals with the controlled influence of the plate tectonism, sea level change and erosional processes in the parent rock source area in the different orders of genetic stratigraphic units. It is proved that the Paleo-Tethys might go through two developing stages: continental sea basin stage and rifled ocean basin stage. |
