| Abstract: | In this paper Cretaceous-Tertiary sedimentary paleostructure and lithofacies-paleogeography in Hailar Basin are described. Taking Chenqi coalfield as an example, the sedimentaryfacies pattern of coal-bearing series characterized by alternating sedimentation of fluviatile and lacustrine-swampy facies is reconstructed. It is pointed out that this sedimentary facies not only controls the sedimentation and distribution of syngenetic uranium mineralization, but also is a favourable place that converges uranium-bearing solution and reduces and precipitates uranium for the second time in epigenetic mineralization. |
