| 中文摘要:围绕加强国内稀土资源勘探和增储上产的迫切需求，笔者在综合研究前期地质资料的基础上，对攀西牦牛坪外围龙家沟开展了以稀土找矿为主的多学科交叉综合调查评价工作。经钻探验证，龙家沟ZK001孔深部发育厚大高品位稀土矿体，科研指导找矿取得突破性进展。161件岩芯样品电感耦合等离子体发射光谱分析结果表明：钻孔ZK001总稀土氧化物（TREO）平均含量达4.87%，见矿视厚度125.76 m，核心部位高品位矿段超过60%。牦牛坪外围龙家沟厚大隐伏稀土矿体的发现与钻探验证，扩大了牦牛坪稀土矿外围的成矿前景，是科技创新指导找矿突破的又一典型实践。随着冕宁-德昌稀土成矿带成矿机制、精准勘查理论技术难题的突破、交叉学科以及模拟技术的应用，将进一步带动该区稀土找矿工作。今后，有必要持续开展牦牛坪外围稀土矿产综合地质调查工作，大幅提升中国第二大稀土资源基地的资源保障能力，对确保中国稀土资源的绝对优势地位具有重要现实意义。 |

| First stage prospecting breakthrough and revelation of Longjiagou REE orebody in periphery of Maoniuping, Sichuan Province, China |

| Abstract:Focusing on the urgent needs of strengthening domestic exploration and increasing reserves and production of rare earth resources, based on the comprehensive study of the preliminary geological data, the project team has carried out a multidisciplinary cross-cutting and comprehensive investigation and evaluation work mainly focusing on rare earth prospecting for the Longjiagou area in the periphery of Maoniuping, west of Sichuan Province. After drilling verification, the project team initially encountered a thick rare earth ore body with high-grade REE in Longjiagou, the periphery of Maoniuping. 161 sample conducted by ICP-AES shows the average content of total rare earth oxides (TREO) of ZK001 is 4.87%, and the apparent thickness of the ore is 125.76 m, which is a breakthrough progress in the search for minerals under the guidance of scientific research. The high-grade ore section in the core area exceeds 60%. The discovery and drilling verification of the thick and large concealed rare earth ore body in Longjiagou, the periphery of Maoniuping, is another typical practice of scientific and technological innovation guiding the breakthrough of ore search. With the breakthroughs in the mineralization mechanism of the Mianning-Dechang rare earth mineralization belt, the breakthroughs in the theoretical and technological difficulties of precision exploration, the cross-disciplinary as well as the application of simulation technology, the rare earth mineral search in the area will be further driven by the work of rare earth mineralization in the area. Therefore, it is necessary to continuously carry out the comprehensive geological survey of rare earth ore searching in the periphery of Maoniuping, which will significantly enhance the resource guarantee capacity of China's second-largest rare earth resource base, and is of great practical significance to ensure the absolute dominant position of China's rare earth resources. |
