Abstract: During Middle Jurassic period, i.e., the sedimentary period of Lower Zhiluo Formation, the braided channel was a favor-able sand body of uranium reservoir that hosted uranium, and uranium was mainly controlled by palaeogeomorphology and mainly developed in low-lying areas. The Late Jurassic, Early Cretaceous-Paleocene and Eocene-Miocene were main uranium mineralization stages. Palaeogeomorphology controlled the migration of underground water, the distribution of the redox zone and the enrich-ment of uranium deposits. During the Late Jurassic uranium pre-mineralization period, diving leaching caused the migration of uranium-bearing materials from the uplift to the slope and low-lying areas; during the main uranium mineralization period of Early Cretaceous-Paleocene, palaeogeomorphology controlled the direction of the water flow with oxygen and uranium, and the redox zone was distributed mainly in the slope area of the ancient landform.
