摘要
加拿大铀资源量位居世界前列,研究加拿大铀资源时空分布规律可以为我国铀矿勘查开发“走出去”战略提供参考。结合IAEA及多方面资料,从宏观上对加拿大铀矿床类型、铀资源储量、铀矿床时空分布规律进行了梳理归纳。目前加拿大存在9种类型的铀矿床,且主要分布在阿萨巴斯卡盆地、Blind River-Elliot Lake和格林维尔铀成矿省内。铀成矿年代集中在太古宙晚期-古元古代早期、古元古代、中元古代、中-新元古代和古生代。
Canada ranks the top of uranium resources in the world.Research on the temporal and spatial distribution of uranium resources in Canada will provide reference for the"going out"development strategy of China's uranium exploration and development.Based the various data from IAEA,the types,resource reserves and temporal and spatial distribution of uranium deposits in Canada was sorted out in a macroscopic perspective.There are 9 types of uranium deposits in Canada,which are mainly distributed in Athabasca Basin,Blind River-Elliot Lake and Greenville uranium metallogenic provinces.Uranium mineralization ages are concentrated in the Late Archean-Early Paleoproterozoic,Paleoproterozoic,Middle Proterozoic,Middle-Neoproterozoic and Paleozoic.
