| 摘 要： | 沉积序列、沉积相、古流向和物质组成的研究结果表明,日喀则大竹卡组是由洪冲积扇和河流相形成的陆相碎屑岩组成。冈底斯火山弧岩系不仅是形成大竹卡组的沉积物源,而且也是大竹卡组沉积盆地的基底,大竹卡组是新近纪造山过程中形成的一个前陆盆地。

| Abstract: | The depositional sequence of sedimentary facies,paleocurrent direction and material composition of the research results show that the the Xigaze the Otake card group is the formation of flood alluvial fan and river continental clastic rocks.Gangdese volcanic arc rock series is not only the formation of the the Otake card group sediment source,but also the base of the sedimentary basins of Otake card group,Otake card group is the formation of a foreland basin in the Neogene orogenic processes. |
