本文首先以地浸砂岩型铀矿为重点 ,分 4个阶段概要回顾了世界铀矿勘查和科研工作发展的历史 ,总结了基本的历史经验。其次 ,全面阐述了当前国外地浸砂岩型铀矿地质发展的现状 ,对砂岩型铀矿在世界铀资源中的重要战略地位、矿床分类、时空展布特点和规律及地浸砂岩型铀矿的成矿理论和找矿技术方法的发展现状进行全面剖析 ,重点从构造条件、古气候条件、水文地质条件、岩相古地理和岩性条件及铀源条件等 5个方面对地浸砂岩型铀矿的成矿条件进行了深入分析 ,对 3类表生后生渗入型砂岩型铀矿的评价准则进行了概括性总结。以美国和中亚两个砂岩型铀矿主产区为代表 ,概述了国外地浸砂岩型铀矿勘查技术方法的发展现状。最后 ,在展望世界铀资源供需发展趋势的前提下 ,明确指出我国铀矿地质战线所面临的严峻挑战 ,有针对性地论述了我们应采取 4个方面的战略对策。
Abstract：Firstly,with emphasis on in-situ leachable sandstone-type uranium deposits,the prospecting history of uranium deposits worldwide and its scientific research development are generally reviewed in four steps,and their basic historical experience is also summarized.Secondly,based on the detailed description of current development status of uranium geology of foreign in-situ leachable sandstone-type uranium deposits.the important strategic position of sandstone-type uranium deposits in overall uranium resources all-over-the-world and its classification,spatial-temporal distribution and regulation,and metallogenic condition of sandstone-type uranium deposits are analysed thoroughly in five aspects:tectonics,paleo-climate,hydrogeology,sedimentary facies and lithology, as well as uranium sources;Afterwards,evaluation principles of three types of hypergenic,epigenetic infiltrated sandstone-type uranium deposits are summarized.Based on sandstone-type uranium deposits located two important countries:the United States and Russia,the current development status of prospecting technology for in-situ leachable sandstone-type uranium deposits in foreign countries is outlined.Finally,according to the prospects of supply-demand development of global uranium resources,the author points out seriously that our uranium geology is faced with a severe challenge,and proposes directly four strategic measures that should be taken.
