摘　　要：全世界业已查证的地浸砂岩型铀矿大多为隐伏盲矿,多产于荒漠、戈壁、半丘陵等地理-地球化学景观区内。地勘手段多为规模化、系列化的钻探工作。我国北方中、新生代沉积盆地众多,属于巨型、大中型,厚覆盖的盆地就有20多个,且多为地浸砂岩型铀矿找矿的处女盆地。受国家综合国力及地质背景、铀矿地勘能力的影响,用规模化、系统化的钻探工作显然有悖于中国国情。参照国内外地勘工作经验,依托于地球化学调查为基础的盆地铀矿信息数字化填图可作为我国地浸砂岩型铀矿勘查的新战略。以地球化学调查为基础的盆地铀矿信息数字化填图经济、实用、快速、有效,国内油气地勘中的盆地油气矿藏信息数字化、金矿地勘中的金矿信息数字化、欧洲26国地调所联袂完成的全欧大地铀信息数字化等工作都表明,盆地铀矿信息数字化理应成为我国地浸砂岩型铀矿勘查的新战略。The discovered ISL sandstone-type uranium deposits in all of the world are mostly blind deposits, many of them occur in bleak desert, gobi desert, and semi-hilly land area. Exploration methods for these deposits mainly depend on great and systematic drilling. There are many largemedium size Meso-Cenozoic sedimentary basins in northern China, and over twenty of them are thick overburden basins which are mostly the virgin land for ISL sandstone-type uranium deposit. Due to the comprehensive national power, geological background, uranium exploration ability, great and systematic drilling is not favorable for prospecting ISL sandstone-type uranium deposit in China. According to the exploration and prospecting experiences for mineral ore bodies at home and abroad, uranium information mapping based on geochemical survey of the basins is a new strategy for ISL sandstonetype uranium deposits. It is an economic, practical, fast and effective method, and has been manifested by the performing information digitization for oil ＆ gas resources, gold mineral resources in China and the mapping of uranium information for whole Europe continent.
