摘要
锂铌钽(Li-Nb-Ta)稀有金属是国际上重要的战略性资源,也是中国的紧缺矿种。基于此本文对湖南境内七个重要的锂铌钽(Li-Nb-Ta)多金属矿床进行系统总结,发现其形成与高分异花岗岩密切相关,集中于晚侏罗世和晚白垩世,因此本文认为未来可在储量评价、精细矿物学和成矿机制方面进一步开展工作,从而带动找矿突破。
Lithium-Niobium-Tantalum(Li-Nb-Ta)rare metals are significant strategic resources in the world,and is the scarce minerals in China.Based on this,seven important Li-Nb-Ta polymetallic deposits located in Hunan province were summarized systematically in this paper.They are closely related to highly fractionated granites and formed in the late Jurassic and late Cretaceous.The future work about the reserves evaluation,elaborate mineral study,and mineralization mechanism can be carried out in order to drive the break-through in mineral exploration.
