摘　　要：乌库尔其矿区是20世纪80年代,引进水成铀矿理论开展区域预测和普查找矿中发现的新区.特别是通过近3年的铀矿普查工作,在该区已大致控制远景资源量近数千吨.铀矿主要分布在中下侏罗统第Ⅴ旋回中,并在第Ⅱ、Ⅶ旋回中亦发现部分远景资源量.本文通过对乌库尔其矿区砂岩型铀矿化特征及其控矿因素进行分析和总结,为矿区进一步开展铀矿普查找矿提供依据.Ukurqi ore district was newly discovered after introduction of metallogenic theory of aqueous uranium origin followed by regional prognosis and prospecting, especially during the recent 3 years. The uranium resource mainly occurs within the cycle V of Lower-Middle Jurassic, and partly within the cycles II and VII. The analysis and summary of the characteristics of sandstone-type uranium mineralization and its ore-controlling factors supply a good basis for the future prospecting of uranium deposits.
