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.
