| 摘 要： | 本文论述了山西大同晚古生代含煤地层的沉积特征及其层序地层学意义，该区的含煤地层虽包括碎屑－碳酸盐屑混合滨岸沉积，三角洲沉积及河流沉积三大类，但以河流沉积为主，通过这些沉积相特征的研究，分析了基准面升降沉积相带的迁移规律，总结了碎屑储层和沉积相带分布与层序界面的关系。

| Abstract: | The authors discuss the depositional characteristics and sequence stratigraphic significance of late Paleozoic coal-bearing strata of the Datong area, Shanxi. The coal-bearing strata comprise clastic-carbonate mixed shore zone sediments, delta sediments and fluvial sediments, with fluvial sediments predominating. On the basis of the characteristics of the sedimentary facies, the au-thors analyse the features of the base level rise and fall and migration of sedimentary facies zones, and summarize the relationships between the distribution of the clastic reservoirs and sedimentary facies zones and the sequence boundaries. |
