摘　　要：囊谦盆地位于青藏高原东部 ,研究程度较低 ,倘处于地层格架建立阶段。在野外工作的基础上全面叙述了地层的岩相特征、沉积体系、古流向等。指出盆地沉积环境为近源、快速堆积环境 ,沉积体系不对称分布且相变迅速 ,物源区单一性 。The Nangqian basin locates at the eastern Tibet Qinghai plateau and is on a low study level at present because of its grim environment. The authors describe in details its features such as the surface form, petrologic features, depositional system , palaeo flow etc. Moreover, the authors point out that the sedimentary environment is proximal and quickly accumulated. All provinces disclose the development of the basin and the activity of Zhaqu Fault which controls the basin development.
