摘要
该文在分析地层界面性质的基础上建立了湘桂地区早海西阶段的构造层序地层格架，并据此探讨了研究区早海西阶段的板内伸展裂陷活动及晚期的板内软碰撞以及软碰撞带对湘中同沉积外生矿产的控制意义。
According to the characteristics of the stratigraphic boundaries,this paper establishes the tectono-sequence stratigraphic framework of the Early Hercynian stage in Hunan and Guangxi district.On the basis of the study,the author discusses the intraplate tectonism,the early extensive rift system and the late soft collision,as well as the relationship between the soft collision belts and the exogenetic deposits.
