| 摘 要： | 本文扼要介绍了加拿大萨斯喀彻温省北部比弗洛支地区脉型 (veintype)和阿萨巴斯卡盆地中与不整合面有关的 (Unconformity associated)铀资源概况 ;比较系统地阐述了两类铀矿化成矿作用的共同特征 ,指出控矿的核心因素是热点活动与构造作用的叠加。这从本质上与我国华南铀矿富集区的控矿因素是相似的。因此 ,通过两个铀矿富集区的对比 ,认识铀成矿作用的本质 ,拓宽找矿思路 ,对于探索寻找新成矿区和新类型铀矿具有一定的启发意义。

| Abstract: | This paper briefly introduces uranium resources of unconformity associated uranium mineralization in Athabasca basin and vein type uranium mineralization in Beaverlodge area, Northern Saskatchewan, Canada, and systematically expounds common metallogenic characteristics of the above two types of uranium mineralization. Authors propose that the key factor for uranium me tallogeny is the superimposition of hot spots and tectonic activities, which essentially resemble ore controlling factors of uranium concentrated areas in Southern China. Therefore, by comparing the geologic characteristics of the two uranium concentrated regions it is of important inspiration significance to understand the essential regularities of uranium metallogeny, to expand ideas in prospecting for uranium and explore new types of uranium mineralization and new metallogenically prospective areas in China. |
