世界超大型铀矿床分类方案新构想

摘要

According to the theory of "multi factors and compound genesis", "complexity of mineralization" and "metallogenic series", this paper proposed a new classification idea on the world super-large deposits with the combination of new results on the study of global background for super-large deposits and the model of "conjugation of multi-source and focus of multi-factors". 15 super-large deposits with the reserve over 50 000 t were studied as the cases, 6 types and 13 sub-types of economics-genesis have been divided for the super-large deposit. The classification is discoursed with symbols and words and brief introduction to typical deposit.%20世纪70年代以来,世界超大型铀矿床不断被发现,铀矿的勘查取得了突破性进展,对超大型铀矿床分类的研究逐步引起铀矿地学者的关注和重视.本文根据“多因复成”成矿理论、“成矿复杂性”和“成矿系列”理论(学说),以及超大型矿床全球背景研究新成果,结合“多源共轭-多因聚焦”成矿模式,提出了超大型铀矿床分类方案新构想；选择15个＞50 000t的超大型铀矿床作为分析个例,划分6大类和13种亚类的超大型铀矿床工业-成因型相；以文字加符号的表达方式,设计了分类概表,简示世界主要超大型铀矿床的成矿概貌.
