在许多产铀矿的岩体中都陆续发现了晶质铀矿,从而引起了铀矿地质工作者极大的注意。经过二六二大队和北京三所多年来有工作证实,桃山岩体的花岗岩中是含晶质铀矿的。但以往的工作多局限在与产铀矿有密切关系,面积仅约30平方公里的打古寨岩体的范围内,对整个复式岩体不同时代花岗岩中晶质铀矿的分布规律,特征和成因尚未进行比较深入的研究。为此,我们在二六二大队系统普查晶质铀矿含量的人工重砂取样工作的基础上,补充和重复取了部分人工重砂大样,进行人工重砂半定量分析。然后再分离提纯出晶质铀矿,经多
In many uranium rock mass have been found in the crystalline uranium, uranium geology workers have caused great attention. After 266 Brigade and Beijing have confirmed the work over the years, the peach rock granite is a crystalline uranium. However, most of the previous work was confined within the scope of the Daclutizi rock mass, which is closely related to the uranium mine, covering an area of only about 30 km2. The distribution and characteristics of the crystalline uranium deposits in granite from different times in the whole complex rock mass Genesis has not been more in-depth study. Therefore, on the basis of the sampling of artificial heavy sand sampled by the 266th Brigade System for the content of crystalline uranium, we added and repeated some artificial heavy sand samples for semi-quantitative analysis of artificial heavy sand. Then separate and purify the crystalline uranium, by more
