摘要
研究区位于青藏高原北缘阿尔金铜金成矿带,处于祁连-昆仑构造带、柴达木陆块和塔里木陆块之间.若羌县库木萨依花岗伟晶岩型锂矿具较高的分异程度,轻重稀土分量不明显,可能来源于地壳物质的部分熔融,构造环境为北阿尔金洋回转引起的俯冲环境.通过对库木萨依花岗伟晶岩型锂矿地质特征、矿床成因及资源潜力的研究,为阿尔金地区寻找类似锂矿资源提出方向.
Abstract
The research area is located in the Altun Copper Gold Metallogenic Belt on the northern edge of the Qinghai Tibet Plateau,situated between the Qaidam block,the Qilian-Kunlun orogenic belt,and the Tarim block.The Kumusayi granite pegmatite type lithium deposit in Ruoqiang County has a high degree of differentiation,and the light and heavy rare earth components are not obvious.It may be derived from partial melting of crustal materials,and the tectonic envi-ronment is a subduction environment caused by the rotation of the North Altun Ocean.By studying the geological charac-teristics,genesis,and resource potential of the Kumusayi granite pegmatite type lithium deposit,this study provides guid-ance for searching for similar lithium resources in the Altun region.
