Abstract: Studying lithology-lithofacies characteristics of Lower Xishanyao Formation, the main uranium-bearing stratum, in Kuosijiaer area of Yili Basin, summarizing it's relationship to uranium deposit, it will provide important theory evidence for following uranium exploration in the study area. Based on the characteristics of lithology, lithofacies structure of connecting-well profile, development of sand bodies, plane distribution of lithofacies structure, and combined with sedimentary geological features of the whole southern margin of Yili Basin, our analysis suggests that the sedimentary subfacies of mainly ore-bearing layer, the Lower sub-member of Lower Xishanyao Formation Middle Jurassic in Kuosijiaer area was fan delta front, and sedimentary micro-facies including the underwater distributary channel with distribution direction towards north and northeast and interdistributary estuary was further detected. Through the study of relationship between lithology-lithofacies characteristics and uranium deposit of target intervals in the study area, the uranium ore bodies occurred in Lower Xishanyao Formation in Kuosijiaer area were mainly controlled by the distribution direction of distributary channel sandbody, the thickness of distributary channel sandbody, the hydrodynamics of sedimentation, the shape or sudden change of sedimentary micro facies, and the post-sedimentary tectonic evolution.
