摘要
铀矿床分类是一个涉及面广又比较复杂的问题,对找矿勘探具有十分重要的指导意义。文中首先对世界上铀矿地质学家按矿床成因,大地构造单元、主岩特征等各种分类方案的优缺点同存在的疑问进行了评述。然后根据中国铀矿成矿特点,在原有4大类型分类基础上,吸收了国外分类方案合理部分,以主岩为主要依据并兼顾矿床构造和矿体形态进行了分类,提出了我国铀矿床分类方案,共划分7大类25个亚类。为引起我国广大铀矿地质工作者的重视和深入讨论,文章最后对有关矿床分类进行了说明和探讨。
The classification of uranium deposits is a comprehensive and complicated problem which is of great importance for the guide in prospecting and exploration. This paper reviews the merits and shortcomings of various classifications sumitted by uranium geologists in the world based on origin, geotectonics and host rocks. Considering the reasonable parts in previous classifications and characteristics of uranium metallogenesis in China, the authors suggest a new classification of uranium deposits of China mainly according to host rocks, and also depo- sits' structure and morphology of ore bodies. This classification is composed of 7 groups divided into 25 subgroups. Finally, an indication and explanation are presented in order to draw attention of the Chinese uranium geologists and make further discussion among them.
