| 摘 要： | 无锡嵩山下三叠统碳酸盐浅滩相剖面在中下扬子区具有特殊性和代表性。碳酸盐滨岸浅滩相剖面不仅最灵敏地记录了海平面变迁历史，而且具有独特的副层序结构和特殊的层序识别和研究方法，在层序地层研究中占有重要地位。借助于与微古地理相结合的副层序分析方法，在嵩山下三叠统露头剖面上共识别出３个２类三级层序，并分别讨论了各层序的发育特点和识别分析方法。

| Abstract: | The Lower Triassic carbonate bank section of Songshan, Wuxi is particular and typical in the Middle and Lower Yangtze Region. The littoral carbonate bank section has not only the most sensitive records of the sea level change, but also the distinctive parasequence pattern and the inimitable method of sequence recognition and analysis. Thus it is of great significance in the study of sequence stratigraphy. Based on the analysis of the parasequence related to the microgeography and the field observation, three third-order sequences of second type have been distinguished in the Lower Triassic outcrop of Songshan, Wuxi and discussed in detail in this paper. |
