| 中文摘要: |
| 随着中国社会经济发展的需要、能源结构的调整及环境的管护，中国铀原料的供需矛盾十分突出。中俄蒙毗邻的额尔古纳成矿带拥有世界上最大的火山岩型铀矿床，但该成矿带中国部分至今未取得找铀突破，蒙古部分虽有突破但工作程度依然较低。随着“一带一路”及“走出去”战略的推进，该成矿带是我国北方获取铀原料的重要来源地。本文通过总结该俄罗斯后贝加尔地区铀成矿的地质特征，分析该区域重磁信息及深部地质与成矿的信息，建立了区域铀找矿模型。这对于指导我国企业在中俄蒙三国毗邻区开展铀矿找矿工作，获取境外的铀矿资源，在我国境内实现铀找矿突破，保障我国的能源安全，具有重要的指导意义。 |
| 英文摘要: |
| With the increasing demand for the development of Chinese economy, the adjustment of energy structure as well as the management and protection of environments, there exists a striking contradiction between supply and demand of uranium in China. The Erguna metallogenic belt, which is in proximity to China, Russia and Mongolia, hosts the biggest volcanic type uranium deposit in the world. So far, however, no breakthrough has been made in uranium prospecting in the part of this metallogenic belt located within China. Despite a few breakthroughs in uranium prospecting in the Mongolian part, the survey work remains at a low level. As the strategies of “The Belt and Road” and “Go globally” are being carried forward, this metallogenic belt has become an important uranium source in the north of China. By summarizing the geological characteristics of uranium deposits in the Zabaikalsky area of Russia, this article analyzes regional gravity and magnetism data as well as deep geology and metallogenic information and establishes a regional uranium prospecting model for this area. It would be a guide to our enterprises to carry out uranium prospecting in the adjacent areas of China, Russia and Mongolia, acquire oversea uranium resources, make breakthroughs in uranium prospecting in China and guarantee the domestic energy security. |
