探讨四川若尔盖铀矿田铀的成矿地质条件，为成矿预测和找矿靶区选择提供依据。通过对若尔盖铀矿田主要矿床的野外地质调查、资料的综合分析研究，结果表明若尔盖铀矿的形成与富铀古陆块、富铀沉积建造、多期次的岩浆活动和富铀岩体、区域性深大断裂带、中新生代陆相红色砂砾岩盆地、有利的岩石组合及其物理力学性质等区域地质背景和条件有着十分密切的关系。若尔盖铀矿田西部矿带的集中分布和一系列有利于铀成矿的良好地质条件，表明若尔盖地区是铀成矿的有利地区，仍存在寻找隐伏富大铀矿的巨大潜力。

The paper studies the uranium mineralization geological conditions of the Ruoergai uranium field in Sichuan of China to provide the basis for the metallogenic prediction and selecting the prospecting target areas.Through the field geological survey of the main uranium ore deposits of Ruoergai and the integrative data analysis,the results show that the formation of uranium ore deposits in this area is closely related with the very favourable geological settings and conditions.These include the uranium-rich old landmass, the uranium-rich sedimentary and rock masses, the magmatic activities,the intermediate-acid intrusive rocks containing uranium,the great deep fault belt,the continental red sandy conglomerate basin of Mesozoic-Cainozoic era,the favorable rock associations and their physcomechanical properties etc.The relatively clustered distribution of the uranium deposits in the west ore belt of the Ruoergai uranium ore field and the very favorable geological settings and conditions for uranium mineralizations suggest that the Ruoergai area is the target area for searching the rich and giant blind ore deposits.
