| 摘 要： | 通过简要介绍依据航磁数据推断地质构造的主要方法,分析总结了花岗岩型、火山岩型、碳硅泥岩型和砂岩型等4大类型铀矿的航磁预测要素特征,并分析了利用航磁推断的地质构造与铀成矿的关系,总结了各类型铀矿的预测要素组合模式。最后以桃山-诸广铀成矿带为例阐述了航磁数据处理与研究对铀资源潜力评价的作用及取得的主要成果。认为航磁数据处理与研究是铀资源潜力评价的重要组成部分。依据航磁数据推断的断裂、侵入岩体及火山构造可以判别有利的构造环境,识别有利的控矿构造,预测有利的成矿部位,对铀资源潜力评价和铀矿普查找矿具有重要意义。

| Abstract: | The article introduces the main methods to deduce geological structures with aeromagnetic data,and summarizes the prediction elements of aeromagnetic characteristics for granti,volcanic,carbonaceous-silicious-argilaceous rock and sandstone type uranium deposits.By analysing the relationship of aeromagnetic deduced geological structures and uranium mineralization,the prediction model of combined factors was summarized for each type uranium deposit.A case study in Taoshan-Zhuguang mineralization belt shew that the fault,plutons and volcanic structures deduced from areomagnetic information can judge the favorable mineralization environment and ore control structure.Therefore,the process and application of aeromagnetic data can play an important role in the evaluation of uranium resource potential and uranium exploration. |
