| 摘 要： | 兰州－民和盆地早白垩世充填了巨厚的陆源碎屑物，笔者通过对碎屑物组合方式的研究，陆盆内为冲积扇相→湖泊相→湖控三角洲相序的充填序列；通过对陆盆的基底特征，古流向、物源区和陆盆演化的分析，揭示了盆地的沉积特征。

| Abstract: | The tremendous terrigenous sediments laid down in the Lanzhou-Minhe Basin during the Early Cretaceous. These Creatceous sediments mainly consist of a succession of lacustrine-dominated red clastic rocks and mudstones, and display a depositional sequence of alluvial fan facies, lacustrine facies and lacustrine-dominated delta facies. The deposition and evolution of the basin are discussed in detail on the basis of basin basement, palaeocurrent and provenance analysis. |
