摘要
本文介绍了采用裂变径迹方法研究碱交代作用中铀在岩石主要矿物中的赋存状态的变化 ,结果表明 ,经碱交代作用 ,岩石中主要造岩矿物的铀含量明显降低 ;含铀副矿物大部分消失 ,铀被带出 ;裂变径迹方法可以直观、定量地用于成矿元素在矿物中迁移的研究。
This paper introduces changes of existing state of uranium in principle rockforming minerals during alkalic metasomatism using fission-track method. Research results show that uranium content in main rock-forming minerals significantly decreases, and most uranium-bearing accessory minerals disappear, and uranium is removed from the rock after alkalic metasomatism. Authors suggest that fissiontrack method may be directly and quantitatively applied to the research on the migration of oreforming elements in minerals.
