战略新兴产业矿产地质调查工程新一轮找矿进展与启示

    Progress and implication for the new round of mineral exploration in Strategic Emerging Industry Mineral Geological Survey

    • 摘要: 近年来,由中国地质调查局组织实施的战略新兴产业矿产地质调查工程在“五稀”(指稀有金属、稀土金属、稀散金属、稀贵金属和稀有气体)矿产新一轮找矿方面取得了一系列新进展。围绕阶段目标任务,通过《中国矿产地质志》的研编和关键矿种的潜力评价,正式出版了志书88部,其中萤石、镍矿、锑矿等战略性矿产全国性矿种组志书19部、省级志书10部,累计完成了200多部志书稿的评审验收,涵盖“书、图、库、普”,在全国实现了矿种、矿产地和成矿区带的全覆盖; 厘定了一批重要矿集区、远景区和靶区,为新一轮找矿突破战略行动的部署提供了依据; 从战略性新兴产业发展的角度选择难度较大的矿种和工作区开展了找矿试点示范,取得了四川阿坝州加达大型锂矿资源基地的找矿突破并促成探矿权招拍挂,取得了四川凉山州牦牛坪南部外围龙家沟和北部外围环单沟稀土矿的找矿突破,为牦牛坪国家级大型稀土资源基地的增储上产作出了贡献,取得了新疆阿尔金锂矿、南方砂矿型锆铪矿、幕阜山北缘铍铌钽矿、天山硼矿等其他一批找矿新成果,为新一轮找矿突破战略行动的实施奠定了基础。在成矿理论、成矿规律、隐伏矿体深部探测、绿色调查评价等方面实现了重大科技创新,并经实践证明具有推广应用价值,可为新一轮找矿突破战略行动的实施提供理论和技术支撑。

       

      Abstract: In recent years, the project of Strategic Emerging Industry Mineral Geological Survey, organized and implemented by China Geological Survey, has achieved a series of new advancements in the new round of mineral exploration for “five rare” minerals. After the compilation of the Mineral Geological Atlas of China and potential assessments of key minerals, 88 volumes of the atlas have been officially published focusing on the phased objectives and tasks. Among them, 19 national-level mineral group atlases covering strategic minerals such as fluorite, nickel ore, and antimony ore, as well as 10 provincial-level atlases, have been completed and published. A total of over 200 atlas manuscripts, encompassing “books, maps, databases, and popularization,” have undergone review and acceptance, achieving full coverage of mineral types, mineral localities, and metallogenic belts nationwide. A series of important mineral concentrations, prospective areas, and target areas have been identified, providing basis for the deployment of the new round of strategic action for breakthroughs in mineral exploration. From the perspective of the development of strategic emerging industries, pilot demonstrations for mineral exploration have been carried out for minerals and working areas with greater difficulty, resulting in breakthroughs in the mineral exploration for Jiada large-scale lithium resource base in Aba Prefecture of Sichuan Province, and facilitating the auction of exploration rights. Besides, breakthroughs have also been made in mineral exploration for rare earth deposits in Longjiagou on the southern periphery and Huandangou on the northern periphery of Maoniuping in Liangshan Prefecture of Sichuan Province, contributing to the increase in reserves and production at Maoniuping national-level large-scale resource base. Furthermore, a number of new mineral exploration achievements have been made, including lithium deposits in Altun Mountains of Xinjiang, placer zirconium and hafnium deposits in South China, beryllium-niobium-tantalum deposits on the northern edge of Mufu Mountains, and boron deposits in Tianshan Mountains, laying the foundation for the implementation of the new round of strategic action for breakthroughs in mineral exploration. Significant technological innovations have been achieved in metallogenic theory, metallogenic regularities, deep exploration of concealed ore bodies, green survey and evaluation, and other aspects. Those innovations have shown their value in promotion and application after practice, providing theoretical and technical support for the implementation of the new round of strategic action for breakthroughs in mineral exploration.
