| 中文摘要: |
| 利用大兴安岭地区1/5万高精度航放资料，对圈定的HFU-09号航放异常开展了综合查证，采用的工作手段包括剖面、面积性查证及深部钻探验证。在钻孔中发现了低品位铀矿体、铀矿化体、铅锌矿化体及铌钽矿找矿线索。根据查证结果认为，1:5万航空物探调查圈定的航放异常与地面伽玛能谱测量圈定的U、Th异常对应性较好，异常再现性较明显。区内岩石破碎铁染发育部位一般存在矿化。在对赋存于花岗岩中的航放异常进行查证时，需结合岩石的具体矿化蚀变特征进行贵金属、有色金属矿产的评价，以期发现多金属矿床。 |
| 英文摘要: |
| Using the greater 1:50000 high-precision airborne radioactive daa in the Hinggan Mountains region, this work has verified the detected HFU-09 aeroradioactive anomalies. The work methods included profile and area examination, and deep drilling confirmation. In drilling holes, low-grade uranium ore bodies, uranium mineralization, lead-zinc mine mineralization and niobium tantalum ore prospecting clues were discovered. The results show that these airborne radioactive anomalies correspond well to the U and Th anomalies determined by gamma-ray spectroscopy on the ground, with good consistence. There exist prevail mineralization at the localities of much iron dissemination in broken rock. When such verification is performed to granite, alternation features of rock should be taken into account for evaluation of precious and nonferrous metals so as to find polymetallic ore deposits. |
