摘要: 不整合脉超大型铀矿床是20世纪60年代后期在加拿大和澳大利亚发现的一种新类型.其最大特点是矿床均产于不整合面附近,矿床既大又富,矿床储量达数十万吨,品位最高达50%,是世界上经济效益很好的铀矿类型.辽东地区在前寒武纪地层内存在5个不整合面,且著名的连山关铀矿床产于元古宇-太古宇不整合面附近,具有不整合脉型铀矿的特征,显示出该区不整合脉超大型铀矿床较好的找矿前景.虽然20世纪90年代曾在该区进行过此类型找矿工作,但由于战略调整而停止.随着我国"十五"期间核电迅猛发展对铀矿资源的需求,继续开展该类型铀矿床的找矿工作具有重要的现实意义.

Abstract: Unconformable vein super-large uranium deposit, a new type of uranium deposit found in Canada and Australia in 1960s, is characterized by occurrence near unconformity surface with high grade and huge reserves. There exist four unconformity surfaces in Precambrian in east Liaoning Province. The famous Lianshanguan uranium deposit is hosted near the unconformity surface between Archaeozoic and Proterozoic strata. It is then concluded that eastern Liaoning is a prospective area for searching unconformable vein super-large uranium deposits.
