摘　　要：大别造山带陆壳成熟晚、稳定程度差，基底变质深、铀源差，缺乏稳定型沉积盖层，铀找矿前景不佳。大别地块与胶东地体有相似的金成矿地质背景，是一个值得高度重视的找矿区段。在对区域成矿规律和当前铀矿经济技术条件分析的基础上，就区内铀金矿产勘查方向提出了五点建议。Prospect of Uexploration may not be optimistic in the Dabie orogenic belt because of its late mature, bad stability of crust, the deep metamorphism, poor uranium source of the basement rocks and lack of stable sedimentary cover. Since Dabie Block has the same geological condition of gold mineralization as Jiaodong terrain, it is an important prospecting region. Based on the regional mineralization regularity and economic technical condition of uranium deposits, the authors give 5 propositions about the exploring direction of uranium and gold in the studied region.
