摘要
塔什达坂锂矿床位于阿尔金稀有金属成矿带的东段,锂矿体赋存于花岗质伟晶岩中,已圈定23条含锂花岗伟晶岩脉,含锂矿物主要为锂辉石、锂云母和锂电气石,伟晶岩脉主要为含锂电气石伟晶岩、锂辉石伟晶岩、锂云母伟晶岩及不含矿黑色电气石伟晶岩,矿物分带明显,其中ρ52号脉特征矿物变化最典型.塔什达坂锂矿床一区南部ρ52～ρ59、ρ58～ρ70之间的区 域存在隐伏矿体,通过矿床地质特征及矿物分带研究,为区域锂矿的勘查评价提供找矿方向.
Abstract
The Tashdaban lithium deposit is located in the eastern section of the Altun rare metal metallogenic belt.Through field geological investigation and comprehensive research,this paper focuses on identifying the geological char-acteristics and mineral zonation characteristics of the Tashdaban lithium deposit,and summarizes the prospecting rules,in order to provide guidance for the follow-up exploration work.The Tashdaban lithium deposit occurs in granitic pegma-tite,23 lithium-bearing granite-pegmatite veins have been delineated in this deposit,and the lithium-bearing minerals are mainly spodumene,lepidolite and lithium tourmaline.The pegmatite veins can be divided into black tourmaline pegma-tite,lithiumite pegmatite,lithiumite pegmatite and lithiumite pegmatite,with obvious mineral zonation.Among them,the mineral changes of ρ52 vein are the most typical.These characteristics indicate that there are hidden ore bodies between ρ52-ρ59 and ρ58-ρ70 in the southern part of the first area of Tashdaban lithium deposit,and the exploration and evaluation should be strengthened.
