| 摘要: |
| 通过内蒙古固阳渣尔泰山群的岩性、岩相和相序研究,对其进行了层序分析和层序划分,识别出一级、二级、三级层序界面,包括海侵沟蚀面和暴露-淹没复合型层序界面。共划分出1个超层序,3个大层序和8个层序。总结出渣尔泰山群的不同古地理背景如碎屑滨岸、台缘碳酸盐岩与碎屑岩混积、碳酸盐台地、台前斜坡和陆棚盆地层序发育模式以及内部构成特征,并探讨了复合海平面变化以及对层序发育和演化的控制作用。 |

| Abstract: |
| Stratigraphic sequences and sequence boundaries are divided for the Zha'ertaishan Group, Guyang, Inner Mongol on the basis of lithological, sedimentary facies and facies sequence approaches.The sequence boundaries consist of the first-, second- and third-o rder sequence boundaries, including transgressive ravinement surfaces and composite exposure-drow ning bounding surfaces. With different scales of sequence boundaries as bounding surfaces, the following sequences have been recognized for the Group:one supersequence, three megasequences and eight sequences.The models for the sequence development and architecture are presented for the different paleogeographic settings of the Zha'ertaishan Group, i. e. siliciclastic shoreline, mixed platform-margin carbonate rocks and siliciclastic rocks, carbonate platform, foreslope and shelf-basin sequences. In addition, the composite sea-level changes and their controls on the sequence development and evolution are also treated in this paper. |
