| 中文摘要: |
| 通过地面放射性能谱等物探方法，对小兴安岭地区1∶5万高精度航放测量圈定的HF101异常开展综合查证工作。采用的工作手段为多道能谱剖面性、面积性查证圈定地面异常，开展槽探、钻探工程验证，最终在探槽及钻孔内部发现低品位铀矿化体、铌钽铷矿化体等找矿线索。通过研究铀异常的分布形态、花岗岩体的产出、变形相、铀矿物元素组合等特征，属加里东期花岗岩外接触带型铀矿（化）；通过成矿条件分析，认为下一步找矿工作应围绕花岗岩体与构造汇聚部位开展。 |
| 英文摘要: |
| Geophysical methods, such as the ground radioactive energy spectrum etc. are used to carry out comprehensive check of anomly HF-101 outlined with high precision airborne radioactive survey at scale 1:50000. The ground anomly is outlined by means of multi-channel and areal check and low grade U mineralization and niobium an tantalum and rubidium mineralization are hit by trenching and drilling. Based on morphology of U anomly, occurrence of granite body, deformation phase and U mineral assemblage it is considered that the mineralization is of out contact zone type of Caledonian granite. The metallogenic condition is analyzed and the prospecting direction points to surrounding of the granite and intersections of the granite and structures. |
