资本主义世界全部铀矿储量的60％赋存在前寒武纪地盾,其中约90％的铀矿产于含金砾岩中。在前寒武纪地盾以外地区,主要铀矿储量大部分产于南北美洲(美国、阿根廷和其他国家)拉拉米造山带的山间盆地和边缘盆地内,以及分布于欧洲和亚洲的海西造山带内。在西欧,在前寒武纪波罗的地盾以外地区,寻找新的铀矿床,主要是在海西期的造山 About 60% of the total uranium deposit in the capitalist world is found in Precambrian shields, of which about 90% of uranium deposits are in gold-bearing conglomerates. Outside Precambrian shields, most of the major uranium deposits are produced in mountain basins and marginal basins of the Lamive orogen in North and South America (the United States, Argentina and other countries), and in the seas of Europe and Asia West orogenic belt. In Western Europe, looking beyond the Precambrian Baltic Shields for new uranium deposits, mainly in the Hercynian orogeny
