| 摘 要： | 随着新能源汽车产业的快速发展和可控核聚变技术研发的不断突破,锂的战略地位正在不断提升。我国虽然盐湖锂矿储量巨大,但开发利用技术尚待改进; 四川甲基卡等硬岩型锂矿近年取得了较大突破,但勘查水平仍然很低,尤其是钻探深度大多浅于300 m,致使目前锂的对外依存度高达74%。因此,在已知锂矿矿田开展深部找矿的方法研究已经迫在眉睫。开展锂能源金属成矿规律、锂同位素研究、地气测量、深穿透地球化学测量、潜力评价技术方法和找矿方法等研究,是当前锂能源金属矿产资源基地深部探测的重要发展趋势。通过在四川甲基卡、新疆卡鲁安、四川黄金口及贵州大竹园等地开展不同类型、不同成矿条件、不同埋深的锂矿的初步研究,概括了我国锂矿资源的分布特征和成矿规律,提出了找矿方向,即: 在川西甲基卡、可尔因一带根据“五层楼+地下室”模型寻找深部层状锂矿; 在新疆卡鲁安等地预测隐伏岩体的存在并指导找矿; 在四川黄金口通过“钾锂兼探”寻找深部液态锂矿; 在贵州—重庆等地寻找深部沉积型锂矿。

| Abstract: | With the rapid development of new energy automobile industry and the breakthroughs of controlled fusion technology, the strategic position of lithium continues to improve. Although domestic lithium reserves in salt lake deposits are huge in China, the development and utilization technology still needs to be improved. There have been great breakthroughs in prospecting for hard rock type lithium in Jiajika of Sichuan, but the general level of prospecting is still very low, especially that most drilling depths are less than 300 m. The external dependence of lithium in China is up to 74%. So it is extremely urgent to carry out deep lithium energy metal exploration in the known lithium reservoirs. The important trends of deep lithium ore deposits exploration are studying metallogenic regularity of lithium energy metal, lithium isotope, geogas prospecting, deep-penetrating geochemical prospecting, potential evaluation techniques and prospecting methods. By summarizing the general features of different types, metallogenic condition and burial depth of lithium ores including Sichuan Jiajika, Xinjiang Kalu’an, Sichuan Huangjinkou and Guizhou Dazhuyuan, the authors generalized the metallogenic regularity and distribution of lithium resources, and indicated prospecting direction as follows: prospecting deep lithium deposits in Jijika and Keeryin of Sichuan according to the model of "five floors + basement", predicting concealed rocks in Kalu’an of Xingjiang, prospecting the liquid lithium resource by co-exploration of potash and lithium in Huangjinkou of Sichuan, and prospecting the sediment-type lithium resource in Chongqing and Guizhou. |
