| 中文摘要: |
| 湘赣边区自晚三叠世开始进入全新的陆内走滑造山作用阶段,并在白垩纪早期经历了从会聚走滑向离散走滑的转换。对该走滑断裂系统的构造解析及铀矿床成矿地质特征的综合分析表明,NNE向走滑断裂直接控制了区域大规模热液铀成矿作用的发生。对走滑断裂控矿作用的特点进行了详细的讨论。 |
| 英文摘要: |
| The Mesozoic-Cenozoic tectonics in the border area of eastern Hunan and western Jiangxi provinces is marked by a NNE-trending intracontinental strike-slip fault system,which is characterized by structural transformation from convergent to divergent strike-slip deformation initiated from early Cretaceous.Analyses of structural pattern of this regional fault system and mineralization features of uranium ore deposits hosted in the strike-slip faults of various scales indicate that Mesozoic-Cenozoic hydrothermal uranium mineralization was directly controlled by NNE-trending strike-slip faulting.The ore-controlling of this fault system is detailed. |
