摘　　要：2013年以来,大红柳滩稀有金属成矿带新发现了苦水湖锂钾硼矿、喀拉喀锂铍矿、龙门山锂矿等17处稀有金属矿床,取得了重大找矿突破。本文作者在总结稀有金属矿产最新找矿成果的基础上,初步分析了稀有金属成矿规律。研究表明,本区伟晶岩矿床与晚三叠纪S型侵入岩密切相关,赋存在外接触带200m~1500m的锂辉石-钠长花岗伟晶岩脉中,成矿期为晚三叠世,成矿类型为伟晶岩型矿床。Since 2013,17 rare metal deposits such as Kushuihu、Karaka、Longmenshan have been newly discovered in The large Hongliutan rare metal metallogenic belt.The author preliminarily analyzes the metallogenic law of rare metals.The study shows that the pegmatite deposit in this area is closely related to the Late Triassic S-type intrusive rock and exists in the spodumene albite granite pegmatite vein 200m~1500m in the outer contact zone.The metallogenic period is the Late Triassic and the metallogenic type is pegmatite deposit.
