锂能源金属矿产基地深部探测技术示范项目进展

锂作为21世纪的能源金属,已经并仍将在未来的能源结构中占有重要地位.中国锂资源对外依存度将近75％,采矿深度普遍不超过300 m,深部探矿势在必行.为提高中国锂矿深部探测能力,储备一批深部探测技术方法,2017年国家重点研发计划设立锂能源金属矿产基地深部探测技术示范项目.项目由中国地质科学院矿产资源研究所牵头,共十余家单位、78位项目成员参加.通过产学研紧密结合,在川西甲基卡、新疆卡鲁安及四川黄金口等地区深入开展了典型矿床和深部探测技术组合方法等的研究,对贵州务正道地区铝土矿、中国西南地区广泛分布的绿豆岩中锂的富集机制开展了深入研究,在锂的成矿理论、新类型锂资源找矿探索、深部探测技术方法组合等方面取得了一系列新进展,圈定了一批远景区和靶区,有力保障了国家锂能源资源安全.

Progress of the deep exploration technology demonstration project for lithium energy metal mineral base

As an energy metal in the 21st century, lithium has played an important role in the future energy structure and the significance will continue in the future. However, the external dependence of lithium resources in China is nearly 75%, and the mining depth is generally less than 300 m, deep prospecting is imperative. In 2017, the State Key Research and Development Program set up a project "Demonstration of deep exploration technology in lithium energy metal mineral base". Headed by Institute of Mineral Resources, Chinese Academy of Geological Sciences, with 10 institutions and 78 members of the project team, and in close collaboration with the mining enterprises, we carried out the study on lithium metallogenic regularities and multiple deep detection approaches in Jiajika of Sichuan, Kaluan of Xinjiang, Huangjinkou of Sichuan, such as the theory of lithium mineralization and exploration approaches for new types of lithium resources. We have made a series of new progress, identified a number of high prospective areas and target areas, that is crucial for securing the country''s lithium resources supply.
