    摘要:

    文章通过阐述北方中新生代产铀盆地的形成分布及大地构造背景特征,并结合前人对北方几个重要砂岩型铀矿床成矿条件的剖析,从区域(大地)构造、沉积体系、古水动力条件、铀源等方面对比分析北方中新生代盆地盆山演化与砂岩型铀成矿作用的关系。认为中新生代的盆山演化对北方产铀盆地及其砂岩型铀矿床的形成分布具有决定性作用。铀成矿作用以层间氧化为主,叠加沉积成岩和潜水氧化成矿,使铀的成矿过程具有多期次、多方位的特点。为下一步在北方各大中小型盆地进行砂岩型铀矿床继续勘查和预测具有一定的借鉴意义。

    Abstract:

    The article fist elaborates the formation and distribution of Meso-Cenozoic U-productive basins and Tectonic background characteristics in the northern China. Combining previous analysis of metallogenic conditions for several important sandstone-type uranium deposits in the north, the paper contrasts and analyses the relationship between basin-mountain evolution and sandstone-type uranium mineralization of Meso-Cenozoic U-producyive basins in northern China from the aspects of regional tectonics, sedimentary system, ancient hydrodynamic conditions and uranium source, etc. It is thought that Meso-Cenozoic basin-mountain evolution has a decisive role in the formation and distribution of U-productive basins and sandstone-type uranium deposits in north China. Uranium mineralization is given priority to interlayer oxidation, with superimposed sedimentary diagenesis and diving oxidation mineralization. It makes the process of mineralization have the characteristics of multiple stages and multidirectional. For the next step of sandstone-type uranium deposit’s continueing exploration and prediction in each big,medium and small basins of the north China, it has a certain significance.
