前寒武纪地台中的结晶地盾很久以来就认为是含有大量铀矿资源的地区,远在四十年代初期,在加拿大和南非地盾就发现了丰富而足够大的矿床(欣科洛布韦,拉吉港),提供了大都分开采铀矿。最近几十年来,在加拿大和南非地盾的元古代砾岩中,在加拿大和其它地盾的长期活动的断裂带的长石交代体中开采了铀矿和含金铀矿床。七十年代初期,在北澳大利亚发现了铀矿床,从而使澳大利亚地盾成为一个巨大的含铀地区。目前在世界铀矿储量表中前寒武纪地盾的矿床占有非常重要的位置。仅在资本主义和发展国家中估计铀矿总储量4百万吨,前寒武纪地盾占1.6百万吨;而从已勘探的铀矿工业储量中的126万吨,前寒武纪的储量占一半以上。
Crystallized shields in the Precambrian platform have long been considered to be areas containing large amounts of uranium resources, and in the early 1940s abundant and large enough deposits were found in the shields of Canada and South Africa Wei, Lagui Harbor), provided mostly separated uranium mining. In recent years, uranium and gold-bearing uranium deposits have been mined in feldspar metamorphic bodies of the long-active fault zones in Canada and other shields in the Proterozoic conglomerates of the Canadian and South African shields. Uranium deposits were discovered in North Australia in the early 1970s, making the Australian Shield a huge uranium-bearing area. The deposits of Precambrian shields currently occupy a very important position in the world uranium reserve table. Only 4 million tons of uranium reserves and 1.6 million tons of Precambrian shields have been estimated in capitalist and developing countries only; while from the 1.26 million tons of proven uranium industrial reserves in the Precambrian More than half of reserves.
