摘要: 在野外实地考察和综合研究的基础上,根据层序界面特征和凝缩层,思茅盆地二叠系可分为9个Ⅲ级层序,其中下二叠统3个,上二叠统6个。根据区域特点,认为二叠纪可分为2个Ⅱ级层序,在思茅盆地范围,乃至中国南方可以进行对比。

Abstract: The Permian strata in the Simao Basin, Yunnan may be divided, on the basis of sequence boundaries and condensed horizons in combination with the field observations along the Zhendong-Dehua sections, into two second-order sequences and nine third-order sequenes including three Lower Permian sequences and six Upper Permian sequences. These sequences may be well compared both throughout the basin and even southern China, implying that a correlation can also be made in eustatic fluctuations, tectonism and sedimentary evolution in southern China.
