摘　　要：不整合面型铀矿床是世界铀资源的主要矿床类型之一,具有重要的经济价值。我国对不整合面型铀矿床的探索一直没有重要突破。在概述不整合面型铀矿床勘查发现历史、分类的基础上,重点介绍了国际原子能机构最新的经验勘查模型分类及以雪茄湖(Cigar Lake)、麦克阿瑟河(McArthur River)、鹰角(Eagle Point)和千年(Millennium)矿床为代表的分类端元矿床地质特征。最后概略分析了我国华北陆块若干地区不整合面型铀矿成矿条件和找矿前景,提出进一步探索不整合面型铀矿床的工作建议。Unconformity-related uranium deposits are one of the most important types of uranium resources in the world and have a great economic value. The exploration for unconformity-related uranium deposits has achieved no important findings for several decades. In this paper, we summarized briefly the world’s exploration history and classifications of unconformity-related uranium deposits, and reported in detail the new empirical classification of unconformity-related uranium deposits and its four end members represented by Cigar Lake, McArthur River, Eagle Point and Millennium deposits all in the Athabasca basin. The conditions and prospecting potential for unconformity-related uranium deposits in North China are analyzed to provide some suggestion on further prospecting for unconformity-related uranium deposits.
