| 摘 要： | 文章以黔东地区含矿主岩为震旦一寒武系碳硅泥岩型铀矿床为例,在分析其成矿条件及地球化学特征的基础上,从区域含铀层、成矿条件等方面对研究区内该类型铀矿的成矿特点进行了分析,认为该类型矿床受莫霍面构造变异部位控制,是深、大断裂长期活动,并导致该区的铀活化、转化,在局部富集的结果。

Geological and geochemical characteristics and genesis of carbonaceous-siliceous-pelitic rock type uranium deposits in eastern Guizhou |

| Abstract: | This paper made a case study of the Sinian-Cambrian carbonaceous-siliceous-pelitic rock type urani-um deposit.Based on the research of the metallogenic conditions and geochemical characteristics of the de-posit,the author analyzed the metallogenic characteristics of this type of uranium deposits inside the study area from the perspectives of uranium-bearing horizons and metallogenic conditions.The author believed that this type of deposits were controlled by structural variation parts of Mohorovicic discontinuity,and long-term activities of the deep fractures caused activation and conversion of uranium in the area and final enrichment in parts. |
