| 摘 要： | 文章研究了ZG复式花岗岩体东南部铀矿床的时、空分布规律与构造活动之间的关系,以及361铀矿床各种构造的控矿、赋矿特征。根据热液脉体及其矿物特征等,分析了成矿热液演化与控矿构造活动之间的关系。361铀矿床构造成矿模式是:在成矿前阶段构造相对挤压的封闭环境中,成矿物质迁移、富集;而在成矿阶段构造拉张的开放环境中快速沉淀成矿。

| Abstract: | In this paper, the relationships between the distribution of uranium deposits located in the southeast of ZG granitic complex in time and space with the tectonic movements are studied. Meanwhile, the ore-controlling and ore-bearing features of various structures in uranium 361 are illustrated. According to the features of hydrothermal veins and minerals, relationships between the evolution of ore-forming solution and the activities of ore-controlling structures are explained. The structural ore-forming model of uranium deposit 36 1 is as follows: in the period of premineralization under conditions of structures being compressed and relatively closed minerogenetic substance migrated and concentrated, however, in the mineralized period within the confines of structures stretching and relatively releasing it was fast precipitated. |
