| 摘 要： | 华北寒武系包括两大套岩系，即辛集组至徐庄组以碎屑岩与碳酸盐岩交互沉积为特征的岩系，代表碳酸盐台地的发展阶段；张夏组至上寒武统的碳酸盐岩系，代表台地的成熟阶段，其中张夏组代表平顶型台地发育阶段，晚寒武世地层形成缓坡型台地的发育阶段。在岩性、岩相、相序研究的基础上，在寒武纪地层中识别出８个三级层序，它们在碳酸盐台地不同的发育阶段，具有不同的相序特征，以及由不同的相序组构代表的、不同的地层堆积作用特点。

| Abstract: | The lithologic and biostratigraphic units from late period of Early Permian to early period of Late Permian in Jiangxi Province and surrounding regions are correlated and subdivided on the basis of the new achievement in palaeontological and biostratigraphic studies. According to the sedimentary features in this period six depositional assemblages are divided: (1) assemblage of shallow marine carbonate platform deposit; (2) assemblage of shallow marine shale siliceous rock; (3) assemblage of shallow marine carbonate shale deposit; (4) assemblage of coastal shallow marine clastic deposit; (5) assemblage of coastal coal bearing clastic deposit; (6) assemblage of basically continental clastic deposit. Finally, the depositional history of this period in Jiangxi Province is discussed. |
