非洲铀资源现状分析

Status analysis on uranium resources in Africa

非洲铀资源量占世界铀资源总量的16%以上。通过对非洲铀资源量、规模品位、矿床类型、成矿时代等基础数据的统计分析,认为非洲的常规铀资源集中在纳米比亚、尼日尔、马拉维和南非,非常规铀资源主要产在摩洛哥。铀矿床主要类型为侵入岩型、砂岩型和石英卵石砾岩型,成矿时代主要是前寒武纪,其次为古生代和中生代。纳米比亚和尼日尔是国内企业走出去在非洲进行铀资源勘查的重要目的地。

Uranium resources in Africa are more than 16% of the world’s. Statistical analysis on essential data such as resources, scale, grade, deposit type and ore-forming age show that the conventional uranium resources concentrate on Namibia, Niger, Malawi and South Africa while unconventional resources as phosphorite type occurred mainly in Morocco. The main types of uranium deposits in Africa are intrusive type, sandstone type and quartz pebble conglomerate type.Precambrian is the main ore-forming epoch while Paleozoic and Mesozoic Era are less important ones.Namibia and Niger should be the target countries for uranium exploration resources for Chinese enterprise abroad.
