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。
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.
