| 摘 要： | 根据贵州紫云扁平剖面沉积记录，分析了该区在二叠纪早期的相对海平面变化特征。研究表明，扁平地区在早二叠世紫松晚期－罗甸期存在6次连续的三级旋回海平面升降过程，其中，海平面上升速率最快的是第3次旋回；水体深度最大的是第4次旋回；海平面上升幅度最大的是第5次旋回。该时期的Ting类生物事件可能与这些特征有关。

| Abstract: | Six continuous sea-level fluctuations across the late Zisong stage to Luodian stage of Early Permian at Bianping area were recognized based on sedimentary records of Bianping Section, Ziyun county, Guizhou province. Among these fluctuations, the third is characterized by highest rate of sea-level rise, the fourth by maximum water depth, and the fifth by supreme uplifted extent. A preliminary analysis has indicated that the heavy loss of fusulinaceans during Early Permian may be related to the above eustatic features. |
