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.
