摘要
通过在福建省建宁县均口火山岩盆地某铀矿床区开展的大功率激电测量的资料分析,揭示了构造深部区域铀矿化密切相关的金属硫化物所形成的二维断面电性异常特征,圈定铀矿化赋存的有利部位。结果表明,铀矿化主要赋存于不同走向断裂构造交汇部位、主构造旁侧的次级构造、裂隙群或接触带部位,其电性特征表现为中低阻、高极化或中低阻、极化率梯级带。
By means of analyzing the data from high--power induced polarization measure- ment carried in a uranium deposit area of the volcanic basin in Fujian Jianning Junkou, this paper reveals the two--dimensional cross--section of anomalous electrical characteristics formed by the metal sulfide which is closely related to uranium mineralization of deep tectonic zone and delimitates the favorable locations in uranium mineralization occurrence area. The results show that uranium mineralization is mainly occurred in the different trend of fracture tectonic intersections, the secondary structure of the main structure flanking, frac- tured group, or parts of contact belt, and the electrical eharacteristies of performance for the low resistivity, high polarization or low resistance polarization rate of the gradient zone.
