摘要
通过对金沙江向家坝水电站Ⅶ坝址地段上三叠统须家河组与地层岩石学特征、剖面结构、沉积构造和粒度分析的研究，指出它们分别属于游荡性河流沉积环境和交织河流沉积环境。
The paper discusses the petrologic characteristics, profile structures and sediment.aryfactes of the Late Tribasic Xujiahe Group at Dam Ⅶ of Xiangjiaba hydroelectric power station,Jinsha River. The results indicates that the formation belongs to a braide river environmentand the formation belongs to an anastornosing river environment.
