| 摘 要： | 西昆仑大红柳滩一带伟晶岩型锂铍等稀有金属成矿带位于康西瓦断裂南侧、大红柳滩-郭扎错断裂北侧,该区内广泛发育三叠纪二长花岗岩,锂铍矿体产于花岗伟晶岩中,近几年的矿产勘查工作,发现了多处具有大型—超大型找矿前景的锂铍等稀有金属矿产地。本次研究在系统收集资料的基础上,确定了锂辉石矿基本特征,开展了成矿条件、成矿规律研究。研究表明该区稀有金属矿的成矿时代为晚三叠世—早侏罗世,矿体受伟晶岩脉控制明显,伟晶岩脉的含矿性与岩体之间空间分布距离具有一定的关系,一般表现为近岩体含矿性差,远离岩体含矿性好的特征。三叠纪岩体周边的伟晶岩脉具有良好的稀有金属矿产的找矿前景,有形成稀有金属矿产接替基地的条件。

| Abstract: | The pegmatite- type rare metal metallogenic belt (such as lithium and beryllium) in the Dahongliutan area of West Kunlun is bounded by the Kangxiwa fault in the north and the Dahongliutan- Guozha fault in the south. The Triassic feldspar granite is widely developed in this area. Lithium and beryllium mineralization occurs mainly in granite pegmatitie. In recent years, the mineral exploration work has discovered a number of large- superlarge rare metal deposits (such as Li and Be) with prospecting potential. Based on the systematic data, this study carried out comprehensive analysis to determine the metallogenic condition and rules of spodumene ore deposits. The study shows that the rare trace deposits formed in the Late Triassic- Early Jurassic. The orebodies are controlled by pegmatite veins. The properties of ore- bearing pegmatite veins have a certain relationship with spatial distribution between rock masses: poor mineralization close to rock mass and good mineralization far from rock mass. Pegmatite veins around the Triassic rocks are of exploraiton prospect for rare metal minerals and are expected to be the production base for rare metal ores. |
