| 摘 要： | 稀有金属是极重要的战略性矿产资源,尤其是高端装备制造业、新能源汽车等新兴产业的发展对其需要量的日益增加,带动了该领域找矿工作取得了一系列新进展。锂、铍、钽是当前最受关注的稀有金属,迄今,我国对于锂等稀有金属成矿机制的研究还不够深入且争论不断。在多年实践的基础上,该文对于锂矿的成矿机制提出了"多旋回深循环内外生一体化"的新认识,并以此拓展了"五层楼+地下室"的勘查模型,进而指导四川可尔因伟晶岩矿田、甲基卡矿田及湘鄂赣交界地区的幕阜山—九岭矿集区、中央造山带的秦巴山区等地在寻找伟晶岩型锂辉石矿床、花岗岩体型锂铍铌钽矿床及层控热液型铍矿床等方面取得新进展,指出了新方向,有助于打开稀有金属找矿的新局面。

| Abstract: | Lithium, beryllium and tantalum are the most important rare metals currently, especially with the increasing demand of emerging industries on rare metals. Moreover, this phenomenon has led the prospecting work to make a series of new progresses. The study of lithium and other rare metals mineralization mechanism is not thorough, and there is still a series of debate around this study. Based on many years of practice, this paper put forward a new understanding of “multi-cycle, deep circulation, integration of internal and external” mechanism for the mineralization of lithium. In addition, the “five levels + basement” exploration model was expanded, and the prospecting work in the Keeryin pegmatite ore field, in the Jiajika pegmatite ore in western Sichuan, in the Mufushan-Jiuling ore district in the Hunan-Hubei-Jiangxi border area, and in the central orogenic belt of the Qinba Mountain, was guided based on the new understanding. New progresses have been made in the program of looking for spodumene deposies of pegmatite type, amblygonite deposits of granite-type and beryllium deposit of strata-bound hydrothermal type, pointing out a new direction and opening a new window for prospecting rare metal deposits in China. |
