    New Progress in Exploration and Development of Global Li-Be-Nb-Ta Resources

    • 摘要: 这是一篇矿业工程领域的论文。锂铍铌钽,既是重要紧缺性稀有金属,也是新兴战略性产业的关键矿产,在成矿规律和勘探开发领域既有共性也有个性并有新的发展。本文力求尽量全面和准确地衡量和评价锂铍铌钽全球资源量和储量数据,及时反映勘探开发新形势和技术新进展。花岗伟晶岩多旋回成矿理论获得重要勘探突破,南美盐湖锂矿技术产量双释放临近,粘土岩和地热卤水提锂增储潜力巨大,碱性-过碱性火山成因-伟晶岩侵入型铌钽成矿在美洲和青藏地区研究深入,中国锂铍矿勘探获重大系列突破,鄂西北铌钽稀土等资源基地建设或可借鉴北美Nechalacho铌钽稀土矿床的勘探和开发经验。本文基于锂铍铌钽矿床和典型案例剖析,提出多期热事件多旋回岩浆分异出熔可能是大型-特大型矿床的关键条件。

       

      Abstract: This is an article in the field of mining engineering. Li-Be-Nb-Ta are not only the important highly-demanded rare metals, but also key minerals in emerging strategic industries. They have both commonality and individuality in mineralization mechanism and R&D with new progress. This article aims to comprehensively and accurately measure and evaluate the global resource and reserve data of Li-Be-Nb-Ta, and timely reflect new developments in exploration and development and technological progress. The multi-cycle metallogenic theory of granite pegmatite has made important breakthrough in exploration, the technical output of lithium deposits in South American salt lakes is approaching, the potential for lithium extraction and storage increase in clay rocks and geothermal brines is increasing, the alkaline-peralkaline volcanic intrusive pegmatite type Nb-Ta mineralization has been highlighted in the Americas and the Qinghai-Xizang region, and the exploration of Li-Be deposits in mainland China has made important breakthroughs. The construction of the resource base for Nb-Ta-REE in northwest Hubei can learn from the progress and experience of enterprise level exploration and testing such as Avalon Rare Metals Company in North America. Based on the analysis of 1396 lithium beryllium niobium tantalum deposits and typical cases in the world, this article proposes that multi stage thermal events and multi cycle magmatic differentiation and melting may be the key conditions for large to super large deposits.
