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。
In this paper, the fission track method is used to study the change of occurrence of uranium in the main minerals in alkali metasomatism. The results show that the uranium content of the major rock-forming minerals in the rock is significantly reduced by alkaline metasomatism. Most disappear, uranium is brought out; fission track method can be intuitive and quantitatively used for mineral element migration in minerals.
