扬子克拉通泥盆纪以来的海相沉积环境演化研究——以扬子克拉通D—T的海相地层剖面为对象

The Marine Sediment Environment Evolution from Devonian in Yangzi Kraton——Regarding the D-T's Marine Stratum in Yangzi Kraton as the Object of Study

根据巢湖北部麒麟山和凤凰山从泥盆系五通组到三叠系南陵湖组的地层剖面与上,中,下扬子地区泥盆系石炭系二叠系三叠系标准剖面进行对比分析,研究其在岩性,岩相方面异同,由此推演当时扬子克拉通不同构造单元内沉积-构造环境的区别与联系,并对扬子克拉通不同构造单元在此段地质历史中的演化做大致分析与综述。

Based on the analysis and comparison of the stratigraphic section from Devonian to Triassic in Qilin and Phoenix hills located in the north of Chaohu lake with the standard sections from Devonian to Triassic in UYB MYB and LYB, approach the difference and similarity in lithology and lithofacies of them, we can figure the difference and relationship of sediment-tectonic environment in different structure units of Yangzi kraton , then analyze and summarize the evolution process of different structure units of Yangzi kraton in this geological history.
